MIC37139
1.5A, Low-Voltage μCap LDO Regulator
General Description
Features
The Micrel MIC37139 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 overtemperature), and
low ground current.
The MIC37139 operates from an input of 2.25V to 6.0V. It
is designed for a wide variety of applications including
digital circuits requiring low-voltage at high currents (i.e.,
PLDs, DSPs, microcontrollers, etc.). It is available in a
fixed output voltage of 1.8V, and as low as 1.5V.
Features of the MIC37139 LDO include thermal and
current-limit protection, and reverse-current and reverse-
battery protection. It’s junction temperature range of the is
