ILC7080AIM5-285

Manufacturer Part Number
ILC7080AIM5-285
Description
50/100M SOT-23 CMOS RF LDO REGULATORS
Manufacturer
IMPALA [Impala Linear Corporation]
Datasheet
The ILC7080/81 are 50 or 100mA low dropout (LDO) volt-
age regulators designed to provide a high performance
solution to low power systems.
The devices offer a typical combination of low dropout
and low quiescent current expected of CMOS parts,
while uniquely providing the low noise and high ripple
rejection characteristics usually only associated with
bipolar LDO regulators.
The devices have been optimized to meet the needs of
modern wireless communications design; Low noise, low
dropout, small size, high peak current, high noise immuni-
ty. The ILC7080/81 are designed to make use of low cost
ceramic capacitors while outperforming other devices that
require tantalum capacitors.
