MIC5256
General Description
The MIC5256 is an efficient, precise CMOS voltage regula-
tor. It offers better than 1% initial accuracy, extremely low-
dropout voltage (typically 135mV at 150mA) and low ground
current (typically 90
μ
A) over load. The MIC5256 features an
error flag that indicates an output fault condition such as
overcurrent, thermal shutdown and dropout.
Designed specifically for handheld and battery-powered de-
vices, the MIC5256 provides a TTL-logic-compatible enable
pin. When disabled, power consumption drops nearly to zero.
The MIC5256 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, critical in hand-held wireless devices.
Key features include current limit, thermal shutdown, faster
transient response, and an active clamp to speed up device
turnoff. Available in the IttyBitty SOT-23-5 package and the
new Thin SOT-23-5, which offers the same footprint as the
standard IttyBitty SOT-23-5, but only 1mm tall. The MIC5256
offers a range of output voltages.
