BA033
Regulator, low drop-out type with ON/OFF
switch
BA ST / BASFP series
The BA ST and BASFP series are variable, fixed output low drop-out type voltage regulators with an ON/OFF
switch.
These regulators are used to provide a stabilized output voltage from a fluctuating DC input voltage.
Fixed output voltages are 3.3V, 5V, 6V(SFP), 7V, 8V, 9V, 10V(ST), 12V(ST). The maximum current capacity is 1 A for
each of the above voltages.
! Application
Constant voltage power supply
! ! ! ! Features
1) Built-in overvoltage protection circuit, overcurrent protection circuit and thermal shutdown circuit
2) TO220FP-5, TO252-5 standard packages can be accomodated in wide application.
3) 0 A (design value) circuit current when switch is off
4) Richly diverse lineup.
5) Low minimum I/O voltage differential.
