The BA178!!T and BA178!!FP series are 3pin fixed positive output voltage regulators. These regulators are used to provide a stabilized output voltage from a fluctuating DC input voltage.
There are 11 fixed output voltages, as follows : 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V, 20V, and 24V. The maximum current capacity is 1A for each of the above voltages.

FEATUREs
1) Built-in overcurrent protection circuit and thermal shutdown circuit.
2) Excellent ripple regulation.
3) Available in TO220FP and TO252-3 packages, to meet wide range of applications.
4) Compatible with other manufacturers regulators.
5) Richly diverse lineup (5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V, 20V, 24V).

APPLICATION
    Constant voltage power supply
