LP3985 - CMOS Voltage Regulator

General Description

The LP3985 is designed for portable and wireless applications with demanding performance and space requirements.

LP3985 performance is optimized for battery-powered systems to deliver ultra low noise, extremely low dropout voltage, and low quiescent current.

Key Features

  • 1 Input Voltage: 2.5 V to 6 V.
  • 100-mV Maximum Dropout with 150-mA Load.
  • 150-mA Verified Output.
  • 50-dB PSRR at 1 kHz at VIN = VOUT + 0.2 V.
  • ≤ 1.5-μA Quiescent Current when Shut Down.
  • Fast Turn-On time: 200 μs (typ. ).
  • 30-μVRMS Output Noise (typical) over 10 Hz to 100 kHz.
  • 40°C to 125°C Junction Temperature Range for Operation.
  • 2.5-V, 2.6-V, 2.7-V, 2.8-V, 2.85-V, 2.9-V, 3-V, 3.1- V, 3.2-V, 3.3-V, 4.7-V, 4.75-V.
