Regulator ICs

Dual output voltage regulator

with power saving

BA51W12ST

The BA51W12ST 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.

FApplications

Car audio systems, VCRs, facsimiles, air conditioners, and other household and industrial equipment

FFeatures

1) Minimum I / O voltage differential is 0.5V or less.

2) Built-in protection circuits against overcurrent, over-

voltage, and overheat.

FAbsolute

maximum ratings (Ta = 25_C)

3) Available in a compact TO220FP-5 package (pins

are bendable).

4) Zero power saving current. (Typ.)

FRecommended

operating conditions (Ta = 25_C)
