Description and Introduction

3-TERMINAL NEGATIVE VOLTAGE REGULATOR The **NJM79L09A** is a fixed negative voltage regulator integrated circuit (IC) designed to deliver a stable **–9V output** with a maximum current of **100mA**. Part of the **79L series** of linear regulators, this component is widely used in low-power applications requiring precise voltage regulation, such as audio equipment, instrumentation, and portable electronics.  

Housed in a compact **TO-92 or SOT-89 package**, the NJM79L09A offers thermal overload protection and short-circuit safeguarding, ensuring reliable performance under varying load conditions. Its low dropout voltage and minimal quiescent current make it suitable for battery-operated devices where power efficiency is critical.  

Unlike adjustable regulators, the NJM79L09A provides a fixed output, simplifying circuit design by eliminating the need for external resistors or feedback networks. However, proper heat dissipation and input/output capacitor selection are recommended for optimal stability.  

With its robust design and consistent performance, the NJM79L09A is a dependable choice for applications requiring a regulated **–9V supply**, particularly in space-constrained or cost-sensitive projects. Engineers and hobbyists alike appreciate its ease of integration and dependable operation in diverse electronic systems.
