• Advantages over SMPS– Smaller, Lower Cost, and Lower EMI– Cap prevents catastrophic failure of the system due to issue on mains– Typically uses lower cost half-wave rectification– Zener adds voltage surge protection

• Disadvantages– Poor efficiency– Limited to low power, light load applications (sub 1W)– LDO output current may be too low for AMR or 3-Phase meters if total power restricted
