This compact CMOS regulator provides a fixed 3.3V single output for low-current electronics projects and embedded hardware. It is rated for up to 200mA output current and is intended for surface-mount designs.

The regulator includes an on/off control input, making it suitable for circuits that need enable control or low-power switching. It is designed for low dropout voltage, low output noise voltage and fast load transient response.

Built-in protection and discharge functions help simplify power rail design, with overcurrent protection and an Auto-discharge function included. A manufacturer datasheet is available for detailed application guidance.

A useful fixed 3.3V regulator for compact PCB designs, sensor supplies and low-power embedded circuits.

Jargon buster

Plain-language definitions for the technical terms used above.

3.3V regulator
A 3.3V regulator is a power circuit that provides a steady 3.3 volts for parts that need that supply voltage. On a breakout board, it can let the sensor run safely even when the connected microcontroller or power source uses a higher voltage.
PCB
A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
transient response
Transient response describes how quickly a circuit or device settles back to a steady state after a sudden change, such as a power supply reacting to a sudden jump in load or an amplifier responding to a fast input. A faster, well-damped transient response means the output stays closer to its target value during sudden changes.
