Product Overview

The LT3021ES8#PBF is a 500mA Very Low Dropout Linear Regulator that operates from input supplies down to 0.9V. This device supplies 500mA of output current with a typical dropout voltage of 160mV. The LT3021 is ideal for low input voltage to low output voltage applications, providing comparable electrical efficiency to that of a switching regulator. The LT3021 regulator optimizes stability and transient response with low ESR, ceramic output capacitors as small as 3.3µF. Other LT3021 features include 0.05% typical line regulation and 0.2% typical load regulation. In shutdown, quiescent current typically drops to 3µA. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting with hysteresis and reverse-current protection. The LT3021 is available as an adjustable output device with an output range down to the 200mV reference. Three fixed output voltages 1.2, 1.5 and 1.8V are also available.
  • Adjustable output (VREF = VOUT (min) = 200mV)
  • Fixed output voltages (1.2, 1.5, 1.8V)
  • Stable with low ESR, ceramic output capacitors (3.3µF minimum)
  • 0.2% Load regulation from 0 to 500mA
  • 120µA Typical quiescent current
  • 3µA Typical quiescent current in shutdown
  • Current limit protection
  • Reverse-battery protection
  • No reverse current
  • Thermal limiting with hysteresis
