Microchip Linear Voltage Regulator 6V 1A Low Dropout SOT-223 3-Pin MIC37100-3.3WS

Microchip MIC37100-3.3WS is a linear voltage regulator designed for low voltage, high current power management applications. Featuring a proprietary Super βeta PNP® pass element, this voltage regulator provides exceptionally low dropout voltage typically 280 millivolts at a 1 ampere output current, enabling efficient regulation down to low input voltages.

This device is housed in a low-profile 3-pin SOT-223 surface-mount package measuring 6.5 mm length, 3.5 mm width, and 1.6 mm height, suitable for compact PCB designs. It offers a guaranteed minimum output current of 1 ampere with excellent initial output accuracy of 1%, making it ideal for precise regulation tasks.

The MIC37100-3.3WS supports input voltages ranging from 2.25 volts to a maximum of 6 volts, delivering regulated output at 3.3 volts. Its low quiescent ground current of 11mA and fast transient response minimize power loss and improve efficiency in portable and battery-operated devices.

Safety features include current limiting and thermal shutdown protection to prevent damage during fault conditions. Additionally, reverse leakage protection enhances reliability in power supply circuits.

This voltage regulator is ideal for embedded systems requiring stable 3.3V power rails under varying loads. Common use cases include industrial control, telecommunications, instrumentation, and consumer electronics applications where precise low voltage regulation is critical.
