Description
The 79M15 is a high-performance, fixed-output negative voltage regulator designed to provide a stable -15V supply from a negative input voltage. As a key member of the 79M series, this regulator is optimized for applications requiring up to 500mA of output current. It is an essential component for split-supply systems, such as those powering operational amplifiers, audio circuits, and data converters that require a precise negative rail.
Housed in a heat-dissipating DPAK (TO-252) surface-mount package, the 79M15 is engineered for efficient thermal management in medium-load applications. It incorporates robust internal safety features, including thermal overload protection, short-circuit current limiting, and safe-area compensation. These protections ensure that the regulator and your sensitive downstream components remain safe even under unexpected fault conditions, providing long-term reliability for your electronic designs.
