The 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 to drive digital circuits requiring low-voltage at high currents (i.e., PLDs, DSPs, microcontrollers, etc.). It is available 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 -40°C to +125°C.
Additional Features
1.5 A minimum guaranteed output current
500mV maximum dropout voltage over-temperature
Ideal fir 3.0V to 2.5V conversion
