L7812 Description

Short technical summary and product information.

The STMicroelectronics L7812 is a versatile positive linear voltage regulator designed for a wide range of applications. It provides a stable 12V output voltage with a maximum output current capability of 1.5A. The device operates with an input voltage range up to 35V and features a typical voltage dropout of 2V at 1A.

 

Key electrical characteristics include a quiescent current of 6 mA and a Power Supply Ripple Rejection (PSRR) of 60dB at 120Hz. For enhanced reliability and protection, the L7812 incorporates over-temperature and short-circuit protection mechanisms.

 

This regulator is housed in a TO-220-3 package and is designed for through-hole mounting. Its operating temperature range spans from -40°C to 125°C, making it suitable for various environmental conditions. The L7812 is a component within the broader category of Integrated Circuits (ICs), specifically Power Management PMICs, and falls under Linear Voltage Regulators.
