BAOOT / FP series

Regulator ICs

Low saturation voltage type 3-pin regulator

BAOOT / FP series

The BAΟΟT/ FP series are fixed positive output low drop-out type, 3-pin voltage regulators with positive output.. These regulators are used to provide a stabilized output voltage from a fluctuating DC input voltage.

There are 10 fixed output voltages, as follows:3V, 3.3V, 5V, 6V*, 7V, 8V, 9V, 10V, 12V and 15V. The maximum current capacity is 1A for each of the above voltages. (Items marked with an asterisk are under development.)

!Applications

Constant voltage power supply

!Features

 

1) Built-in overvoltage protection circuit, overcurrent

3) Compatible with the BA178ΟΟ series.

protection circuit and thermal shutdown circuit.

4) Richly diverse lineup.

2) TO220FP and TO252-3 packages are available to

5) Low minimum I / O voltage differential.
