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.
