General Description

The MIC5256 is an efficient, precise CMOS voltage

regulator. It offers better than 1% initial accuracy,

extremely low-dropout voltage (typically 135mV at 150mA)

and low ground current (typically 90µA) 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

devices, the MIC5256 provides a TTL-logic-compatible

enable pin. When disabled, power consumption drops

nearly to zero.

The

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

package and the new Thin SOT-23-5, which offers the

same footprint as the standard IttyBitty

only 1mm tall. The MIC5256 offers a range of output

voltages.
