General Description
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.
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.
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.
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.
