A negative voltage linear regulator (negative LDO) is a linear power management IC designed to generate and stabilize a fixed negative DC output voltage from an unregulated negative input voltage. It features low dropout voltage, ultra-low output noise, simple peripheral circuits, and no switching ripple. It provides clean negative power rail for analog and signal circuits.
Application Scope：
1.Provide negative bias voltage for operational amplifiers,comparators and analog front-end circuits.
2.Supply positive/negative dual power rails for sensors,audio circuits and signal conditioning modules.
3.Precision instrumentation,industrial measurement equipment and medical electronic circuits.
4.Communication RF modules,high-precision ADC/DAC reference power supplies.
5.Low-current,low-noise scenarios that require stable negative voltage without switching interference.
