Negative Power Supply for Op-Amps
Generate a clean -5V to -15V rail for precision operational amplifiers in audio or instrumentation circuits. The 77dB PSRR at 120Hz effectively rejects mains hum.
Adjustable Negative Bias Supply
Use the adjustable output down to -37V to bias avalanche photodiodes (APDs) or tune the operating point of RF amplifiers and mixers.
LCD Contrast Control
Provide a stable negative voltage for LCD VCOM or contrast adjustment in industrial displays, ensuring consistent image quality over temperature.
Industrial Sensor Power
Power negative-rail sensors and transducers in process control systems. The 1.5A capability supports multiple sensors from a single regulator.
Audio Preamplifier Supply
Create a symmetric supply with a positive LDO for high-end audio preamps. The low noise and high PSRR preserve signal fidelity.
Test & Measurement Equipment
Use as a programmable negative reference in benchtop instruments. The D2PAK package allows efficient heat dissipation for continuous operation.
