L7912ACV Description

Short technical summary and product information.

The L7912ACV from STMicroelectronics is a three-terminal negative voltage regulator designed for local on-card regulation. It offers a fixed output voltage of -12V and can deliver an output current of up to 1.5A, provided adequate heat sinking is employed. This series is particularly suitable for split power supplies.

 

Key features include thermal overload protection and short circuit protection, enhancing device reliability and system robustness. The regulator is available in a TO-220 package, suitable for through-hole mounting. Its operating temperature range is from 0°C to 125°C.

 

With a typical voltage dropout of 1.1V at 1A and a PSRR of 60dB at 120Hz, the L7912ACV is a reliable choice for various power management applications. While primarily designed as fixed voltage regulators, they can be used with external components to achieve adjustable voltages and currents.
