Description
The SPX1117M3-3.3 is a low-dropout (LDO) linear voltage regulator from Exar (now MaxLinear). It provides a fixed 3.3V output with a maximum current of 800mA and a low dropout voltage (typically 1.1V at 800mA).
Key features:
- Input voltage range: Up to 15V
- Low quiescent current: ~5mA
- High accuracy: ±1% output tolerance
- Protections: Overcurrent and thermal shutdown
- Package: SOT-223 (compact, surface-mount)
Commonly used in battery-powered devices, embedded systems, and consumer electronics for stable voltage regulation. Requires minimal external components (input/output capacitors).
For detailed specs, refer to the datasheet.
