ONSEMI MC7915CTG Negative Voltage Regulator, -15V, 1A, TO-220

The ONSEMI MC7915CTG is a robust, fixed-output negative voltage regulator, designed as the ideal complement to the widely used MC7800 series positive regulators. It features a low-dropout (LDO) design in a rugged TO-220 package, engineered to deliver stable -15V output with a maximum current of 1A when provided with adequate heat-sinking. This component is remarkably rugged, thanks to its integrated current limiting, thermal shutdown, and safe-area compensation, which protect the device under most demanding operating conditions.

A key advantage is its simplicity of use; no external components are required for basic operation. Its comprehensive internal protection includes thermal overload protection and short-circuit current limiting, ensuring reliable performance and safeguarding connected circuits. The regulator operates across a broad industrial temperature range from 0°C to 125°C, making it suitable for a wide array of applications.

With a typical dropout voltage of 1.3V, it efficiently regulates input voltages from -23V down to -35V, providing a consistent and precise -15V output. Its through-hole mounting and classic three-pin TO-220 configuration make it easy to integrate into prototypes, development boards, and final production designs alike. This regulator is an essential component for any power supply section requiring a reliable, negative voltage rail.
