MIC37152WR-TR

The MIC37150, MIC37151, MIC37152, and MIC37153 are 1.5A low-dropout linear voltage regulators that provide low voltage and high current output with a minimum of external components. They offer high precision, ultra-low dropout (500 mV over temperature), and low ground current. The MIC37150/1/2/3 operate from an input of 2.25V to 6.0V. They are designed to drive digital circuits that require low voltage at high currents (i.e., PLDs, DSPs, microcontrollers, etc.). They are 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 MIC37150/1/2/3 LDOs include thermal and current-limit protection, reverse current protection, and reverse battery protection. Logic enable and error flag pins are available. Junction temperature range of the MIC37150/1/2/3 is from -40℃ to +125℃.
