General Description
The MIC5252 is an efficient, precise CMOS voltage regulator
optimized for ultra-low-noise applications. It offers 1% initial
accuracy, extremely-low dropout voltage (135mV at 150mA)
and low ground current (typically 90μA). The MIC5252
provides a very-low-noise output, ideal for RF applications
where a clean voltage source is required. The MIC5252 has
a high PSRR even at low supply voltages, critical for battery
operated electronics. A noise bypass pin is also available for
further reduction of output noise.
Designed specifically for handheld and battery-powered
devices, the MIC5252 provides a TTL-logic-compatible en-
able pin. When disabled, power consumption drops nearly
to zero.
The MIC5252 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, critical in handheld wireless devices.
Key features include current limit, thermal shutdown, faster
transient response, and an active clamp to speed up device
turn-off. The MIC5252 is available in the 6-pin 2mm

2mm
MLF package and the IttyBitty SOT-23-5 package in a
wide range of output voltages.
