General part information

The LD39200 provides 2 A of maximum current with an input voltage range from 1.25 V to 6.0 V, and a typical dropout voltage of 130 mV.

It is stable with ceramic capacitors on the output (10 µF).

Typical power supply rejection ratio is 70 dB at 1 kHz and starts to roll off at 20 kHz.
