MIC37300/37301/37302
Micrel, Inc.
MIC37300/37301/37302
3.0A, Low-Voltage Cap LDO Regulator
General Description
The Micrel MIC37300/01/02 is a 3.0Alow-dropout linear volt-
age 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 operates from an input of 2.25V to
6.0V. It is designed to drive digital circuits requiring low-volt-
age at high currents (i.e., PLDs, DSP, microcontroller, etc.).
It is available in xed 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 LDO include thermal and
current-limit protection, and reverse-current protection.
Logic enable and error ag pins are available on the 5-pin
version.
Junction temperature range of the MIC37300/01/02 is from
–40°C to 125°C.
For applications requiring input voltage greater than 6.0V,
see the MIC3910x, MIC3915x, MIC3930x, and MIC3950x
LDOs.
