BA00BC0WFLDO Regulator With Shutdown Circuit

BA00BC0WF is a PNP output LDO

regulator IC with the output current of 0.5A

and a voltage accuracy of ± 2%.

Output voltage can be set (1.5V to 12V) by

external resistor. Over-current protection

circuit and thermal protection circuit are

incorporated to prevent IC from being

damaged by short and thermal break down.

SOP8

• This product is not designed for protection against radioactive rays.

*1 Designed Guarantee.(Outgoing inspection is not done all products.)

* All characteristics are measured with a capacity across the input of 0.33µF and a capacity across the output of 0.22µF. Measurement is done at Ta Tj, and variations in the parameter of all measurement(expect Temperature Coefficient of Output Voltage)caused by temperature change are not considered.
