Description and Introduction

3-TERMINAL NEGATIVE VOLTAGE REGULATOR The **NJM79L12A** is a fixed negative voltage regulator designed to provide a stable -12V output with a maximum current of 100mA. As part of the **79Lxx** series, this IC is widely used in low-power applications where precise voltage regulation is essential. Its compact TO-92 package makes it suitable for space-constrained designs, while its built-in thermal overload and short-circuit protection enhance reliability.  

Operating within an input voltage range of **-14.5V to -35V**, the NJM79L12A ensures consistent performance with minimal output fluctuations. Its low dropout voltage and low quiescent current make it an efficient choice for battery-powered devices and portable electronics. Additionally, the regulator requires minimal external components—typically just input and output capacitors—for stable operation.  

Common applications include **audio circuits, instrumentation, and small-scale power supplies**, where maintaining a steady negative voltage is critical. Engineers favor the NJM79L12A for its simplicity, cost-effectiveness, and dependable performance in both industrial and consumer electronics.  

For optimal results, proper heat dissipation and adherence to recommended operating conditions should be considered during circuit design. The NJM79L12A remains a practical solution for low-current, negative voltage regulation needs.
