BA44W12SAT
Regulator ICs
Dual output voltage regulator with power
saving
BA44W12SAT
The BA44W12SAT is a general-purpose power supply with outputs : 8V, 1A and 8V, 500mA. The IC is available in a
compact TO220FP-5 package. The outputs can be turned off during the power saving state with a built-in switch. Also
built in the IC are an overcurrent protection circuit, an overvoltage protection circuit, and a thermal shutdown circuit.
