Description and Introduction

3-TERMINAL NEGATIVE VOLTAGE REGULATOR The **NJM79L03UA** is a low-power, fixed negative voltage regulator designed to deliver a stable -3V output with a maximum current of 100mA. Part of the NJM79L series, this IC is widely used in applications requiring precise voltage regulation, such as portable electronics, instrumentation, and small-scale power supplies.  

Built with advanced semiconductor technology, the NJM79L03UA offers low dropout voltage, thermal overload protection, and short-circuit current limiting, ensuring reliable performance under varying load conditions. Its compact **TO-92** package makes it suitable for space-constrained designs while maintaining efficient heat dissipation.  

Key features include a low quiescent current, minimal output noise, and high ripple rejection, making it ideal for battery-operated devices and noise-sensitive circuits. The regulator requires only a few external components, simplifying circuit design and reducing overall system cost.  

Engineers often choose the NJM79L03UA for its robustness, ease of integration, and consistent performance across industrial and consumer applications. Whether used in analog signal processing, microcontroller power supplies, or auxiliary voltage regulation, this component provides a dependable solution for maintaining stable negative voltage rails.  

For optimal performance, proper heat sinking and decoupling capacitors should be considered, particularly in high-load or high-temperature environments.
