BA178!!T / FP series
Regulator ICs
Standard 78 series, 3-pin regulator
BA178!!T / FP series
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.
