BA05T

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BA05T is a fixed positive standard regulator with a nominal output voltage of 5V and a maximum output current capacity of 1A. It operates within an input voltage range of 6V to 25V and features a low dropout voltage typical value of 0.3V at 0.5A load. The device provides high ripple rejection and includes built-in overcurrent, thermal shutdown, and overvoltage protection circuits. It is housed in a TO-220FP package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What capacitors are recommended for preventing oscillation?

A 22µF capacitor between the output pin and GND is recommended, preferably a tantalum electrolytic capacitor with small ESR. A 0.33µF bypass capacitor should be connected close to the input pin and GND.

How does the overcurrent protection circuit behave?

The circuit limits current in a '7' shape to prevent IC destruction. It has a high margin to prevent latching even with large capacitance loads but is not intended for continuous protection.
