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.
!Applications
Car audio systems, VCRs, facsimiles, air conditioners, and other household and industrial equipment
!Features
1) Minimum I / O voltage differential is 0.5V or less.
2) Built-in protection circuits against overcurrent, over voltage, and overheat.
3) Available in a compact TO220FP-5 package (pins are bendable).
4) Zero power saving current. (Typ.)
