79L09 Negative Voltage Regulator IC (TO-92, -9V, 100mA)

The 79L09 is a low-current negative linear voltage regulator designed to provide a regulated -9V DC output from a suitable negative input voltage. Its compact TO-92 through-hole package makes it suitable for space-constrained electronic circuits, dual power supplies, analog systems, and signal processing applications. The regulator helps maintain a stable negative voltage rail for compatible circuits and typically includes internal thermal and overload protection, depending on the manufacturer and device variant.
