The LM79L24 from TAEJIN is a fixed negative linear regulator providing -24V output at up to 100mA. Housed in a TO-92 package, it offers a dropout voltage of 1.7V at 40mA and a quiescent current of 6.5mA. With a PSRR of 33dB at 120Hz, it delivers stable negative supply rails for analog circuits, industrial sensors, and audio equipment. Its simple three-terminal design requires minimal external components.
- Fixed -24V Output: Simplifies design by eliminating the need for external resistor dividers.
- 100mA Output Current: Sufficient for powering op-amps, sensors, and bias circuits.
- TO-92 Package: Through-hole package is easy to solder and breadboard-friendly.
- Low Quiescent Current (6.5mA): Reduces power consumption in always-on applications.
Negative Rail for Op-Amp Circuits
Many precision analog circuits require a negative supply rail. The LM79L24 provides a stable -24V output from a more negative input, enabling dual-supply operation for operational amplifiers in audio and instrumentation equipment.
Bias Supply for LCD Displays
Some LCD panels require negative bias voltages for proper contrast control. The LM79L24's fixed -24V output is suitable for such applications, providing a clean and regulated bias source.
Industrial Sensor Interfaces
Industrial transducers and sensors often need bipolar supplies. The LM79L24 can generate the negative rail needed for signal conditioning circuits, ensuring accurate measurement in process control systems.
Audio Equipment Power Supply
High-fidelity audio amplifiers use symmetric power supplies to eliminate output coupling capacitors. The LM79L24 provides the negative -24V rail, complementing a positive regulator for clean audio power.
Telecom Line Cards
Telecommunication equipment uses negative voltages for line driver circuits. The LM79L24 offers a simple, low-cost solution for generating a regulated -24V supply from a -30V or lower input.
Test and Measurement Instruments
Benchtop multimeters and oscilloscopes require multiple supply rails. The LM79L24's TO-92 package is easy to integrate into PCB designs, providing a reliable negative reference for measurement circuits.
