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
protection circuit and thermal shutdown circuit.
2) TO220FP and TO252-3 packages are available to
cover a wide range of applications.
3) Compatible with the BA178ΟΟ series.
4) Richly diverse lineup.
5) Low minimum I / O voltage differential.
