2A LDO Regulators

BDxxFD0 series

Description

The BDxxFD0 series are low-saturation regulators. The

series’ output voltages are Variable, and fixed type.

These series have a built-in over-current protection

circuit that prevents the destruction of the IC due to

output short circuits and a thermal shutdown circuit that

protects the IC from thermal damage due to overloading.

Features

 Output current capability: 2A

 Output voltage: Variable, Fixed

(1.5V / 1.8V / 2.5V / 3.0V / 3.3V / 5.0V / 8.0V

/ 9.0V / 12V / 15V / 16V)

 ±1% (±1.5%:BD15/18/25FD0W)

High output voltage accuracy (Ta=25°C)

 Low saturation with PDMOS output

 Built-in over-current protection circuit that prevents

the destruction of the IC due to output short circuits

 Built-in thermal Shutdown circuit for protecting the

IC from thermal damage due to overloading

 Low ESR Capacitor

 HRP5/TO263-5 package
