L7912CP Description

Short technical summary and product information.

The STMicroelectronics L7912CP is a three-terminal negative voltage regulator designed for a wide range of applications. It provides a fixed output voltage of -12V and can deliver an output current of up to 1.5A when adequate heat sinking is provided.

 

Key features include thermal overload protection and short circuit protection, ensuring reliable operation. The device is available in a TO-220FP package, suitable for through-hole mounting.

 

This regulator is useful for on-card regulation, helping to eliminate distribution problems associated with single-point regulation. It is particularly suited for split power supplies when used with the L78xx positive standard series. While designed as a fixed voltage regulator, it can be adapted for adjustable voltage and current applications with external components.

 

The operating temperature range is from 0°C to 125°C, and it has a maximum input voltage rating of -35V. The PSRR is 60dB at 120Hz, and the voltage dropout is typically 1.1V at 1A.
