BA41W12SAT Datasheet Dual Output Voltage Regulator With Power Saving

Manufacturer: ROHM

Overview: BA41W12SAT Regulator ICs Dual output voltage regulator with power saving BA41W12SAT The BA41W12SAT is a general-purpose power supply with outputs : 8V, 1A and 8V, 500mA. The IC is available in a pact 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.
