STMicroelectronics L7915CV -15V 1.5A Voltage Regulator TO-220

The STMicroelectronics L7915CV is a single-gauge, three-terminal negative voltage regulator that delivers a fixed -15V output voltage. It is designed for a wide range of applications requiring a stable and reliable negative supply rail, and it is especially well-suited for split power supply configurations when paired with the corresponding L78 positive series.

This regulator provides local on-card regulation, effectively eliminating the distribution issues commonly associated with single-point regulation. When adequate heat sinking is provided, it can deliver over 1.5A of output current, making it a robust solution for various power management tasks.

While primarily a fixed voltage regulator, the device can be used with external components to achieve adjustable voltages and currents, offering flexibility for custom designs. Built-in protection features include thermal overload protection, short-circuit protection, and output transition SOA protection. The output tolerance is 2% (AC version) or 4% (C version) at 25°C.

The L7915CV comes in a standard TO-220 package, suitable for through-hole mounting, and operates within a temperature range from 0°C to 150°C. Its compact design and reliable performance make it an ideal choice for power management applications that require a precise negative voltage output.
