Tổng quan
Description
- Input Voltage Range: Up to 15V (typical).
- Dropout Voltage: ~1.1V at 800mA load.
- Output Current: Up to 1A (with proper heat dissipation).
- Low Quiescent Current: ~5mA (typical).
- Protections: Overcurrent and thermal shutdown.
It is commonly used in battery-powered devices, embedded systems, and consumer electronics where stable 3.3V power is required. The CX suffix often denotes a SOT-223 package, offering a compact footprint.
For optimal performance, ensure input voltage ≥ 4.4V and use input/output capacitors (typically 10µF) for stability. Check the datasheet for exact specifications.
