Product Description
The 7812 Voltage Regulator IC is a three-terminal positive linear voltage regulator that delivers a fixed, regulated +12V DC output from a higher unregulated DC input supply. Part of the legendary 78xx family of voltage regulators, the 7812 has been the go-to solution for decades in power supply design, prototyping, and production electronics.
With an input voltage range of 14V to 35V DC and a maximum output current of 1.5A, this IC is ideal for powering 12V relay modules, cooling fans, LED strips, microcontroller boards, and a wide variety of 12V-rated components. The TO-220 package allows easy mounting to a heatsink for high-current applications, and the through-hole pins make it fully breadboard and perfboard compatible.
The 7812 features built-in thermal overload protection, short-circuit current limiting, and safe operating area (SOA) protection, making it extremely robust and forgiving - perfect for beginners and professionals alike. Simply connect a 0.33uF capacitor on the input and a 0.1uF capacitor on the output for stable, noise-free 12V regulation.
Key Features
- Fixed +12V Regulated Output: Delivers a stable 12V DC regardless of input voltage fluctuations (within rated range).
- Up to 1.5A Output Current: Sufficient for powering relays, fans, LED strips, sensors, and motor driver logic supplies.
- Wide Input Voltage Range (14V-35V): Works with a variety of unregulated DC power sources and transformer-rectifier setups.
- Built-In Triple Protection: Thermal shutdown, short-circuit current limiting, and safe operating area protection prevent damage.
- Excellent Ripple Rejection (~55dB): Smooths out AC ripple from rectified power supplies for clean DC output.
- TO-220 Package: Industry-standard through-hole package with a metal tab for heatsink mounting.
- Simple 3-Pin Design: Input, Ground, Output - minimal external components required for operation.
- Drop-In Compatible: Pin-compatible with L7812, MC7812, UA7812, KA7812, and other 7812 equivalents.
- Breadboard & PCB Friendly: Through-hole leads fit standard 2.54mm pitch prototyping boards.
- No External Components Required (Minimum): Works with just two bypass capacitors for basic applications.
