BA41W12SAT
The BA41W12SAT 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.
zApplications
Car audio systems, VCRs, facsimiles, air conditions, and other household and industrial equipment
zFeatures
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.)
