7812 Voltage Controller

7812 Voltage Controller - Pack of 5:

The 7812 is a voltage regulator integrated circuit (IC) from the 78xx series, designed to provide a stable, fixed output voltage of +12 volts. Similar to the 7805 and 7809, which provide +5 volts and +9 volts, respectively, the 7812 is commonly used in electronic circuits where a regulated +12V power supply is required.

Here are the key features of the 7812 voltage regulator:

IC Type: Voltage Regulator (Positive)
Output Voltage: +12 volts (Fixed)
Output Current: Up to 1A (depending on the variant)
Input Voltage Range: Typically around 14V to 25V, with variations based on specific models.
Package Type: Commonly available in TO-220 and TO-92 packages.
Pin Configuration:
- Pin 1 (Input): Connects to the unregulated input voltage.
- Pin 2 (Ground): Common ground reference.
- Pin 3 (Output): Provides the regulated +12V output.

Usage:

The 7812 is commonly used in various electronic circuits to provide a regulated +12V supply. Applications include powering operational amplifiers, analog components, microcontrollers, and other devices requiring a stable +12V voltage source.

Notes:

Decoupling Capacitors: It is advisable to use input and output decoupling capacitors (typically electrolytic or ceramic capacitors) to improve stability and filtering.
Heat Dissipation: Depending on the input-output voltage differential and output current, the 7812 may generate some heat. Adequate heat sinking may be required, especially for higher current applications.
Variants: There are different variants of the 7812, such as the LM7812, UA7812, and more. Always refer to the datasheet of the specific model you are using for accurate information.
