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.
