LDL212

High PSRR, low drop linear regulator IC

Datasheet - production data

Applications



Consumer

Industrial

SMPS

Point-of-load

DC-DC post-regulation

Description

The LDL212 provides 1.2 A of maximum current

from an input voltage range from 2.5 V to 18 V,

with a typical dropout voltage of 350 mV @ 1.2 A.

The high power supply rejection ratio of 87 dB at

120 Hz, and more than 40 dB at 100 kHz, makes

the LDL212 suitable for direct regulation in SMPS

and secondary linear regulation in DC-DC

converters. The LDL212 goes to shutdown mode

due to the enable logic control function, reducing

the total current consumption. The device also

includes the current limit, SOA and thermal

protections.
