General Description

The MIC29150/29300/29500/29750 are high current, high

accuracy, low-dropout voltage regulators. Using Micrel's

proprietary Super βeta PNP™ process with a PNP pass ele-

ment, these regulators feature 300mV to 370mV (full load)

dropout voltages and very low ground current. Designed for

high current loads, these devices also ﬁnd applications in

lower current, extremely low dropout-critical systems, where

their tiny dropout voltage and ground current values are

important attributes.

The MIC29150/29300/29500/29750 are fully protected

against overcurrent faults, reversed input polarity, reversed

lead insertion, overtemperature operation, and positive and

negative transient voltage spikes. Five pin ﬁxed voltage ver-

sions feature logic level ON/OFF control and an error ﬂag

which signals whenever the output falls out of regulation.

Flagged states include low input voltage (dropout), output

current limit, overtemperature shutdown, and extremely high

voltage spikes on the input.

On the MIC29xx1 and MIC29xx2, the ENABLE pin may

be tied to V

MIC29150/29300/29500 are available in 3- and 5-pin TO-220

and surface mount TO-263 packages. The MIC29750 7.5A

regulators are available in 3- and 5-pin TO-247 packages.

For applications with input voltage 6V or below, see MIC3715x LDOs.
