MIC29150/29300/29500/29750

High-Current Low-Dropout Regulators

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

element, these regulators feature 350mV to 425mV (full

load) typical 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 versions 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 VIN if it is not required for ON/OFF control. The

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

TO-220 and surface mount TO-263 (D Pak) packages.

The MIC29750 7.5A regulators are available in 3-pin and

5-pin TO-247 packages. The 1.5A, adjustable output

MIC29152 is available in a 5-pin power D-Pak (TO-252)

package.

For applications with input voltage 6V or below, see

MIC37xxx LDOs.
