MIC37150/51/52/53

1.5A, Low Voltage µCap LDO Regulator

General Description

Features

The Micrel MIC37150/51/52/53 is a 1.5A low-dropout

linear voltage regulator that provides a low voltage, high

current output with a minimum of external components. It

offers high precision, ultra-low dropout (500mV over

temperature), and low ground current.

• 1.5A minimum guaranteed output current

• 500mV maximum dropout voltage over temperature

–

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 MIC37150/51/52/53 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, DSPs, micro-

controllers, etc.). It is available in ﬁxed and adjustable

output voltages. Fixed voltages include 1.5V, 1.65V, 1.8V,

2.5V and 3.3V. The adjustable version is capable of

supplying output voltages from 1.24V to 5.5V.

VIN: 2.25V to 6.0V

• ±1.0% initial output tolerance

• Fixed and adjustable output voltages

ﬁxed voltages with flag

Features of the MIC37150/51/52/53 LDO include thermal

and current limit protection, and reverse current and

reverse battery protection. Logic enable and error ﬂag pins

are available.

–

MIC37152—5-pin adjustable voltage

MIC37153—8-pin adjustable voltage with flag

• Excellent line and load regulation speciﬁcations

• Logic controlled shutdown

• Thermal shutdown and current limit protection

• Reverse-leakage protection

Junction temperature range of the MIC37150/51/52/53 is

from –40°C to +125°C.

For applications requiring input voltage greater than 6.0V,

see MIC3910x, MIC3915x, MIC3930x, and MIC3950x

LDOs.

• Low proﬁle 3 or 5-pin S-Pak packages or 8-pin e-Pad
