LD3985 Overview

Key Specifications

Package: LSSOP
Mount Type: Surface Mount
Pins: 5
Output Type (varies by manufacturer): Fixed

Description

The LD3985 provides up to 150 mA, from 2.5 V to 6 V input voltage. The ultra low drop voltage, low quiescent current and low noise make it suitable for low power applications and in battery-powered systems.

Key Features

  • Input voltage from 2.5 V to 6 V
  • Stable with low ESR ceramic capacitors
  • Ultra low-dropout voltage (60 mV typ. at 150 mA load, 0.4 mV typ. at 1 mA load)
  • Very low quiescent current (85 µA typ. at no load, 170 µA typ. at 150 mA load; max.1.5 µA in OFF mode)
  • Guaranteed output current up to 150 mA
  • Wide range of output voltages: 1.22 V; 1.8 V; 2.5 V; 2.7 V; 2.8 V; 2.9 V; 3 V; 3.3 V; 4.7 V
  • Fast turn-on time: typ. 200 µs [CO = 1 µF, CBYP = 10 nF and IO = 1 mA]
  • Logic-controlled electronic shutdown
  • Internal current and thermal limit
  • Output low noise voltage 30 µVRMS over 10 Hz to 100 kHz
