MIC37300/01/02/03

3.0A, Low-Voltage µCap LDO Regulator

General Description

Features

The Micrel MIC37300/01/02/03 is a 3.0A low-dropout

linear voltage regulator that provides a low-voltage,

high-current output with a minimum number of external

components. It offers high precision, ultra-low-dropout

(500mV overtemperature), and low-ground current.

• 3.0A minimum guaranteed output current

• 500mV maximum dropout-voltage overtemperature

–

Ideal for 3.0V to 2.5V conversion

–

Ideal for 2.5V to 1.8V, 1.65V, or 1.5V conversion

• Stable with ceramic or tantalum capacitor

• Wide input voltage range

The MIC37300/01/02/03 operates from an input of

2.25V to 6.0V. It is designed to drive digital circuits

requiring low-voltage at high currents (i.e., PLDs, DSP,

microcontroller, etc.). It is available in ﬁxed and

adjustable output voltages. Fixed voltages include 1.5V,

1.8V, 2.5V and 3.3V. The adjustable version is capable

of 1.24V to 5.5V.

–

VIN: 2.25V to 6.0V

• +1.0% initial output tolerance

• Fixed and adjustable output voltages:

–

MIC37300—3-pin ﬁxed voltages

MIC37301—5-pin S-Pak or 8-pin e-Pad SOIC

ﬁxed voltages with ﬂag

Features of the MIC37300/01/02/03 LDO include

thermal and current-limit protection, and reverse-current

protection. Logic enable and error ﬂag pins are available

on the 5-pin version.

–

MIC37302—5-pin adjustable voltage

MIC37303—8-pin e-Pad SOIC adjustable

voltage with flag

• Excellent line and load regulation speciﬁcations

• Thermal shutdown and current-limit protection

• Reverse-leakage protection

Junction temperature range of the MIC37300/01/02/03

is from–40°C to +125°C.

For applications requiring input voltage greater than

6.0V, see the MIC3910x, MIC3915x, MIC3930x, and

MIC3950x LDOs.

• Low proﬁle S-Pak package

Data sheets and support documentation can be found

on Micrel’s web site at www.micrel.com.

Applications

• LDO linear regulator for low-voltage digital IC

• PC add-in cards

• High-efﬁciency linear power supplies

• SMPS post regulator

• Battery charger
