LC1117COTR33

The LC1117COTR33 is a low-dropout (LDO) linear voltage regulator from STMicroelectronics, providing a fixed 3.3V output with a 1A current capacity. It features a low dropout voltage (typically 1.2V at max load), making it suitable for applications with tight input-output differentials.
Key characteristics:
- Input voltage range: Up to 15V
- Output voltage: Fixed 3.3V (±2% accuracy)
- Low quiescent current: ~5mA
- Protections: Overcurrent and thermal shutdown
- Package: SOT-223 (compact, surface-mount)
Common uses include powering microcontrollers, sensors, and low-power circuits in consumer electronics, IoT devices, and embedded systems. Its stability with low-ESR capacitors enhances reliability.
For alternatives, check AMS1117 or LM1117, but verify specs for compatibility.
