MIC37502WU [Microchip]

The MIC37501 and MIC37502 are 5A, low dropout linear voltage regulators that provide low-voltage, high-current outputs with a minimum of external components. They offer high precision, ultra-low dropout (500mV), and low ground current.

The MIC37501and MIC37502 operate from an input of 2.3V to 6.0V. They are designed to drive digital circuits requiring 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 1.24V to 5.5V.

MIC37501 and MIC37502 LDOs feature thermal and current limit protection, and reverse current protection. Logic-enable and error flag pins are available.

Junction temperature range of the MIC37501/02 is -40°C to 125°C.

For applications requiring input voltage greater than 6.0V, see MIC3910x, MIC3915x, MIC3930x, and MIC3950x LDOs.
