The LM79L06 from TAEJIN is a fixed negative linear regulator delivering -6V at up to 100mA. Packaged in a TO-92, it features a dropout voltage of 1.7V at 40mA and a quiescent current of 6mA. With a PSRR of 47dB at 120Hz, it provides clean negative supply rails for op-amp circuits, sensor biasing, and portable instrumentation. Its compact three-pin design simplifies PCB layout.
- Fixed -6V Output: Ideal for low-voltage dual-supply analog circuits.
- 100mA Current Capability: Enough for multiple op-amps or sensor loads.
- High PSRR (47dB @ 120Hz): Rejects mains-frequency ripple for clean audio and measurement.
- Low Quiescent Current (6mA): Suitable for battery-powered devices.
Negative Rail for Low-Voltage Op-Amps
Many modern op-amps operate from ±5V supplies. The LM79L06 provides a stable -6V rail, enabling dual-supply operation for audio preamplifiers, active filters, and instrumentation amplifiers.
Biasing for MEMS Sensors
Some MEMS accelerometers and gyroscopes require negative bias voltages. The LM79L06 delivers a clean -6V supply, ensuring accurate sensor readings in automotive and consumer electronics.
Portable Instrumentation
Battery-powered multimeters and handheld testers often need a negative reference. The LM79L06's low quiescent current of 6mA helps preserve battery life while providing the required negative rail.
Audio Mixer Console Supplies
Audio mixing consoles use multiple op-amps that need symmetric supplies. The LM79L06 can generate the -6V rail for low-voltage audio paths, reducing noise and distortion.
Data Acquisition Systems
DAQ systems with bipolar input ranges require negative supplies for ADC drivers. The LM79L06 provides a simple solution for generating -6V from a -8V or lower input.
Automotive Sensor Conditioning
In automotive ECUs, the LM79L06 can power negative-rail circuits for pressure and temperature sensors, ensuring reliable operation in harsh environments.
