MIC5253
100mA Low Noise

Cap Teeny LDO
General Description
The MIC5253 is an efficient, CMOS voltage regulator opti-
mized for ultra-low-noise applications. It offers 1.5% initial
accuracy, extremely low dropout voltage (165mV at 100mA),
and low ground current (typically 95
μ
A at full load). The
MIC5253 provides a very low noise output, ideal for RF
applications where a clean voltage source is required. A
noise bypass pin is also available for further reduction of
output noise.
Designed specifically for handheld and battery-powered de-
vices, the MIC5253 provides a TTL-logic-compatible enable
pin. When disabled, power consumption drops nearly to zero.
The MIC5253 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, critical in handheld wireless devices.
Available in the Teeny SC-70-5 package, the MIC5253
offers a wide range of output voltages. Key features include
current limit, thermal shutdown, faster transient response,
and an active clamp to speed up device turn-off.
