STMicroelectronics L7905CV Voltage Regulator, -5V, TO220-3

The STMicroelectronics L7905CV is a robust 3-terminal negative voltage regulator that delivers a fixed -5V output with a maximum output current of 1.5A. It is designed to simplify power supply designs by providing local on-card regulation, which effectively reduces the distribution issues commonly associated with single-point regulation. This regulator is particularly well-suited for split power supplies, especially when paired with L78 positive series counterparts of the same voltage option, making it a versatile building block for various electronic applications.

The device includes essential protection features to safeguard both the regulator and your circuit: thermal overload protection, short-circuit protection, and output transition safe operating area (SOA) protection. With an output tolerance of 2% (AC version) or 4% (C version) at 25°C, it provides reliable performance. The L7905CV can also be used with external components to achieve adjustable voltage and current outputs, offering design flexibility in addition to its fixed-voltage role.

Packaged in the popular TO-220 through-hole package, this regulator is easy to integrate into a wide range of power management circuits. Its multiple protection mechanisms and robust design make it a dependable choice for engineers and hobbyists alike.
