Micrel

MIC29150/29300/29500/29750 Series

High-Current Low-Dropout Regulators

General Description

Features

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

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

proprietary Super ßeta PNP™ process with a PNP pass

element, theseregulatorsfeature300mVto370mV(fullload)

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.

• High Current Capability

MIC29150/29151/29152/29153................................1.5A

MIC29300/29301/29302/29303...................................3A

MIC29500/29501/29502/29503...................................5A

MIC29750/29751/29752...........................................7.5A

• Low-Dropout Voltage ....................... 350mV at Full Load

• Low Ground Current

• Accurate 1% Guaranteed Tolerance

• Extremely Fast Transient Response

• Reverse-battery and “Load Dump” Protection

• Zero-Current Shutdown Mode (5-Pin versions)

• Error Flag Signals Output Out-of-Regulation

(5-Pin versions)

• Also Characterized For Smaller Loads With Industry-

Leading Performance Specifications

TheMIC29150/29300/29500/29750arefullyprotectedagainst

overcurrent faults, reversed input polarity, reversed lead

insertion, overtemperatureoperation, andpositiveandnega-

tive 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.

• Fixed Voltage and Adjustable Versions

Applications

• Battery Powered Equipment

• High-Efficiency “Green” Computer Systems

• Automotive Electronics

• High-Efficiency Linear Power Supplies

• High-Efficiency Post-Regulator For Switching Supply

On the MIC29xx1 and MIC29xx2, the ENABLE pin may be

tied to V if it is not required for ON/OFF control. The

MIC29150/29300/29500areavailablein3-and5-pinTO-220

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

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