Description

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.

The enable logic control function puts the

LD39200 in shutdown mode, reducing the total

current consumption to 10 nA (typ.).

Power Good flag is available on a dedicated pin.

The device also includes reverse current

protection, short-circuit constant current limit and

thermal protection.

Typical applications are for Telecom

infrastructure and consumer.
