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.

"
"
Application
Constant voltage power supply
"

"
"
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).
