ILC7082
150mA SOT-23 Ultra Low Noise
CMOS RF-LDO™ Regulator
General Description
The ILC7082 is a 150mA low dropout (LDO) voltage regu-
lator designed to provide a high performance solution to
low power systems. The device offers a typical combina-
tion 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 device has been optimized to meet the needs of mod-
ern wireless communications design; Low noise, low
dropout, small size, high peak current, high noise immunity.
The ILC7082 is designed to make use of low cost ceramic
capacitors while outperforming other devices that require
tantalum capacitors.
