The LP3985IM5X-3.3 is a fixed 3.3V LDO linear regulator from Texas Instruments, offering up to 550mA output current. Its ultra-low dropout of 0.1V at 150mA ensures efficient operation from Li-ion batteries. With a quiescent current of 150 μA and PSRR of 50-40dB (1-10kHz), it delivers clean, stable power for portable and RF applications. The compact SOT-23-5 package is ideal for space-limited designs.

  • Ultra-Low Dropout: 0.1V at 150mA extends battery life by allowing operation near end-of-discharge voltage.
  • Compact Size: SOT-23-5 package minimizes PCB footprint for miniaturized devices.
  • Low Noise Operation: 50-40dB PSRR across 1-10kHz ensures clean power for RF and audio circuits.
  • High Current Density: 550mA output in a tiny package supports power-hungry peripherals.
