## Summary description

Riff Voltage Regulator Chip 662K (XC6206P332MR) is a linear LDO regulator providing a fixed 3.3V output at up to 0.5A. Designed for compact electronic designs, it offers stable voltage supply for microcontrollers, sensors, and low-power modules. Suitable for power regulation, prototyping, and repair tasks where a simple, fixed-voltage 3.3V source is required.

## Long description

Riff 662K XC6206P332MR is a compact linear LDO voltage regulator providing a fixed 3.3V output with a maximum load current of 0.5A. Packaged in SOT-23, this regulator is intended for space-constrained electronic designs and supplies a stable 3.3V rail for microcontrollers, sensors and low‑power modules.
Advantages
The XC6206P332MR offers a simple fixed-voltage solution that requires minimal external components, comes in a small SOT-23 package and delivers up to 0.5A output current. Its linear regulation provides low-noise output suitable for analog and digital circuits, and the fixed 3.3V output simplifies power design for common logic levels.
Suitable for
Microcontroller power supply (3.3V logic)
Sensors and small peripheral modules
Prototyping and breadboard projects
Repair and replacement in compact electronic devices
Key specifications
Model: XC6206P332MR (Riff 662K)
Output voltage: 3.3V (fixed)
Maximum output current: 0.5A
Package: SOT-23
Type: Linear LDO regulator
Brand: Riff
MPN: PS-M-662K
EAN: 4422190000971
How to use
Connect the input to an unregulated supply higher than 3.3V (observe the regulator's maximum input rating from the manufacturer's datasheet), connect ground, and place the required input and output capacitors as specified by the datasheet close to the device pins. Use the fixed 3.3V output to power microcontrollers, sensors or other circuits that require a stable 3.3V rail. Ensure adequate PCB layout and thermal considerations when operating near the 0.5A limit.
Usage recommendations
Refer to the official XC6206P332MR datasheet for exact input voltage range, recommended capacitor values and thermal limits. For currents approaching 0.5A, verify power dissipation and consider heat sinking or reduced ambient temperature to maintain reliable operation.
