Dual output voltage regulator with power

saving

BA51W12SAT

The BA51W12SAT is a general-purpose, low saturation power supply with two outputs : 9V, 1A and 5V, 500mA. The IC is

available in a compact TO220FP-5 package. The outputs can be turned off during the power saving state with the built-in

switch. Also built in the IC is an overcurrent protection circuit, an overvoltage protection circuit, and a thermal shutdown

circuit.
