BA51W12SAT

BA51W12SAT Regulator ICs 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.
