STMICROELECTRONICS L7905ACV Voltage Regulator, -5V, TO-220
STMicroelectronics L7905ACV -5V fixed negative voltage regulator, 1.5A, TO-220 package. Ideal for power management and automotive.
The L7905ACV is a three-terminal negative voltage regulator from STMICROELECTRONICS, designed to deliver a fixed -5V output with up to 1.5A of current. This device provides local on-card regulation, effectively eliminating the distribution problems often associated with single-point regulation. When paired with the L78 positive standard series, it becomes particularly suited for split power supply applications, offering a balanced and reliable power solution.
This regulator is built for robust performance, featuring thermal overload protection, short-circuit protection, and output transition SOA protection. The output tolerance of 2% at 25°C ensures stable and accurate voltage regulation. Although primarily designed as a fixed voltage regulator, the L7905ACV can be used with external components to achieve adjustable voltages and currents, providing flexibility for a wide range of design requirements.
