The Story
3.3V 1A Low Dropout Voltage Regulator – TO-220
Reliable 3.3V Low Dropout Voltage Regulator
This 3.3V low dropout voltage regulator is designed for stable, efficient power delivery in your electronics projects. Perfect for Arduino, Raspberry Pi, sensors, and other low voltage devices, this 3.3V LDO regulator provides consistent output even when input voltage is just above 3.3V. Its TO-220 package makes it easy to use on common breadboards and PCBs.
Key Features
- Fixed 3.3V Output: Ensures your sensitive devices get the correct voltage.
- 1A Output Current: Supplies up to 1 amp of steady current for a wide range of single-board computers, microcontrollers, and digital circuits.
- Low Dropout Voltage: Operates with an input as low as 4.5V, maximizing efficiency and minimizing heat generation.
- User-Friendly TO-220 Package: Easy to mount, solder, and heatsink for hobbyists and professionals alike.
Technical Specifications
- Output Voltage: 3.3V DC
- Output Current: Up to 1A
- Input Voltage Range: 4.5V to 5.5V DC
- Package: TO-220, 3-pin
- Part Numbers: VET1904, LM3940
Easy Installation & Usage
Simply connect your positive input voltage (4.5V–5.5V DC) to pin 1 (Input), ground to pin 2 (Ground), and take the regulated 3.3V output from pin 3 (Output). Suitable for breadboards, stripboards, and DIY kits. Heatsinking is recommended for continuous loads near 1A.
Applications
- Power supply regulation for microcontrollers and development boards
- Stable 3.3V power for sensors, WiFi modules, and low-voltage logic circuits
- Projects requiring a 3.3V positive voltage regulator with low dropout and high reliability
Note: Please verify this part’s specifications and pinout before use to ensure compatibility with your project. Original part ID reference: NTE1904 (now obsolete).
