The fixed output models are produced as an equivalent lineup to the μA7800

Series of industrial-standard fixed positive voltage output power supply

regulators developed by Fairechild in 1976.

Output voltages of 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, 15 V, 18 V, 20 V and 24 V

are available. Output voltage tolerance is within 4%. Three output currents 1 A

(BA78xx), 500 mA (BA78Mxx) and 100 mA (BDxxFA1) are available. An approx.

2 to 3 V difference in I/O voltage is required. The lineup does not include

equivalents to the μA7900 Series’ fixed negative voltage output power supply

regulators.

Naming rules

The variable output models are produced as an equivalent lineup to the LM1117,

a low saturation output version of the industrial-standard LM317 released by

National Semiconductor Corporation in 1977. The difference in I/O voltage

follows the LDO specification, by ranging from 2 V to 1.2 V as before. The output

voltage range is from 1.25 V to 8.6 V and output voltage tolerance is within 1%.

Output voltage is 1 A.

Single-Output LDO Regulators 45 V, 50 V rating

The left figure shows a system diagram of 45 V and 50 V rated LDO

type linear regulators. These low quiescent current regulators

feature the following specifications: an output voltage tolerance

within 2% across the entire temperature range, output current of

200 mA or 500 mA, and current consumption of 6 μA to 80 μA. The

small amount of quiescent current is suitable for reducing current

consumption in systems directly connected to batteries. The

BD7xxL2 and BD7xxL5 Series realize an ultra-low quiescent current

of 6 μA, further contributing to a reduction in current consumption.

(Across the entire temperature range)

A low ESR ceramic capacitor is available for output phase compensation.

The built-in output current control circuit prevents damage to the IC by

output short-circuiting.

The built-in thermal shutdown circuit prevents thermal damage to the IC if

overloaded.

The left figure shows a system diagram of 7 V, 10 V

and 15 V rated LDO type linear regulators. These

models feature output currents of 300 mA, 500 mA,

1 A and 1.5 A, and come in automotive and

industrial grades. An output voltage tolerance of

3% is ensured for both grades across the entire

temperature range.

13LINEAR REGULATORS SELECTION GUIDE www.rohm.com

Product example: BD3512MUV

Low Voltage Power Supply Solutions

Input voltage range: 0.7V to (VCC-1)V

Output voltage range: 0.65V to 2.7V

Output current: 3A

High precision standard voltage circuit: 0.65V 1%

N-ch Power MOSFET ON resistance: 65mΩ

Minimum I/O voltage difference: 100mV max (Io=1A, VIN=1.2V)

The soft start prevents rush current at power ON.

Power good output with settable delay

Enable function

Undervoltage lockout circuit (UVLO)

Thermal shutdown circuit (TSD)

Overcurrent protection function (OCP)

This Series of ultra-LDO type linear regulators uses L3RegTM technology, which provides solutions for power supply systems requiring multiple low voltage patterns such as a digital signal

processing LSIs. The ultra-LDO type offers excellent low input voltage operation and low I/O voltage characteristics that ensure great efficiency comparable with a switching regulator. This

also allows a reduction in external parts such as inductors.

Microcontroller Monitoring Power Supply Solutions

Product example: BD3010AFV, BD3020HFP, BD3021HFP

Ultra-low quiescent current: 80µA (Typ)

Output transistor: Pch DMOS low saturated type


Output current: 200mA , 500mA

Output voltage: 5.0V 2%

(Across the entire temperature range)

A low ESR ceramic capacitor is available for output phase compensation.

The built-in watchdog timer monitors for microcontroller hang-ups and

resets the microcontroller in the event thereof, which enables the system

to restart automatically.

The watchdog timer is automatically turned ON/OFF depending on the

load current so as to avoid unnecessary monitoring by the timer when the

microcontroller is in the sleep mode (BD3010).

Forced ON/OFF control enables the watchdog timer to stay OFF until the

system is stable, e.g., when the microcontroller (BD3010, BD3021) starts

up, etc.

The built-in undervoltage output reset (power-on reset) circuit enables

setting of the actuation delay time.

The reset detection voltage is adjustable (BD3010, BD3020).

The built-in output current control circuit prevents damage to the IC by

output short-circuiting.

The built-in thermal shutdown circuit prevents thermal damage to the IC if

overloaded.

The BD3010AFV, BD3020HFP and BD3021HFP are regulators with a rated voltage of 50 V and output current of 200 mA/500 mA. They are power supply ICs that integrate a watchdog

timer (WDT) that monitors for microcontroller malfunctions and a reset circuit that monitors power supply voltage on a single chip.

A low ESR ceramic capacitor is available for output capacitor.

The built-in undervoltage output reset (power-on reset) circuit enables setting of the

actuation delay time.

The power voltage detection reset circuit is built in, which enables monitoring of input power

voltage or other power voltages (BD4269).

The detection voltage for the output low voltage reset circuit and power voltage detection

reset circuit (BD4269) can be adjusted with an external resistor.

The built-in output current control circuit prevents damage to the IC by output short-circuiting.

The built-in thermal shutdown circuit prevents thermal damage to the IC if overloaded.

BD4269FJ-C, BD4269EFJ-C, BD42754FP2-C and BD42754FPJ-C regulators have a rated voltage of 45 V and output current of 200 mA to 500 mA. They are power supply ICs that integrate

a reset circuit for monitoring power supply voltage on a single chip.

Support of JEDEC DDR1/2/3/3L

Product example: BD35395FJ-M

The BD35395FJ-M is a terminal regulator that

supports DDR1/2/3/3L SDRAMs in conformity with

JEDEC. It integrates a VTT power supply, one of the

three power supplies required for the DDR memory.

VTT output is a linear power supply that integrates

an N-MOSFET and is capable of supplying a

maximum 1 A both to the sink and source. The

internal OP-AMP designed for high-speed operation

helps realize excellent transient response

characteristics. To drive the internal N-MOSFET, a

bias power supply of 3.3 V or 5.0 V is required. This

linear regulator possesses an independent standard

input pin (VDDQ) and an independent feedback pin

(VTTS) in order to keep the JEDEC-specified voltage

precision, and contribute to excellent output voltage

precision and load regulation.BD35395FJ-M Application Circuit

A DDR memory needs three power supplies. For

VDDQ, a power supply to drive the memory cell, high-

speed load response and voltage precision are

required in order to assure reliability in memory

operations. Input to the memory cell is judged based

on VREF, which is one-half of VDDQ voltage.

Although the required current value is small, voltage

precision is required in response to changes in VDDQ

voltage. VTT is the termination voltage of the memory

output, which terminates the memory output via a

terminal resistor RT. Its voltage is one-half of VDDQ

and is required to follow changes in VDDQ voltage like

VREF. As the memory output switches to High or Low,

the output current must be capable of following the

source or sink operation at a high speed.

Input voltage range: 2.7V to 5.5V

Output current: 1A
