General Description
The Micrel MIC37150/51/52 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 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, microcontrollers,
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 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 is from
–40
°
C to 125
°
C.
For applications requiring input voltage greater than 6.0V,
see MIC3910x, MIC3915x, MIC3930x, and MIC3950x LDOs.
