General Description

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.

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.

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.

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.
