The LD33CV is a positive linear voltage regulator IC that provides a fixed 3.3V output from higher input voltages. Designed to deliver up to 800mA, it features low dropout voltage, internal current limiting, and thermal protection, making it a dependable choice for powering 3.3V devices.
- Output Voltage: 3.3V (fixed)
- Input Voltage Range: 4.75V – 15V
- Output Current: Up to 800mA
- Dropout Voltage: ~1.1V at full load
- Package: TO-220
- Protections: Short-circuit and thermal shutdown
- Applications: Power supply regulation for 3.3V microcontrollers (ESP32, ESP8266), sensors, and other digital logic systems
The LD33CV is well-suited for projects that require clean and stable 3.3V power, especially in DIY electronics, Arduino-compatible boards, and low-voltage embedded systems.
