MIC37139
1.5A, Low-Voltage
μ
Cap LDO Regulator
General Description
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 preci-
sion, ultra-low dropout (500mV overtemperature), and low
ground current.
The MIC37139 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 avail-
able in fixed output voltages, including 1.5V, 1.65V, 1.8V,
2.5V and 3.3V.
Features of the MIC37139 LDO include thermal and current-
limit protection, and reverse-current and reverse-battery
protection.
Junction temperature range of the MIC37139 is from –40
°
C
to +125
°
C.
