Product Overview

LT3065EDD-1.2#PBF is a micropower, low-noise, low-dropout voltage (LDO) linear regulator that operates over a 1.6V to 45V input voltage range. This device supplies 500mA of output current with a typical dropout voltage of 300mV. A single external capacitor provides programmable low-noise reference performance and output soft-start functionality. Additionally, a single external resistor programs the LT3065’s current limit, accurate to ±10% over a wide input voltage and temperature range. A PWRGD flag indicates output regulation. The LT3065 optimizes stability and transient response with low ESR ceramic capacitors, requiring a minimum of 3.3µF. Internal protection circuitry includes current limiting with foldback, thermal limiting, reverse battery protection, reverse current protection, and reverse output protection. Applications include battery-powered systems, automotive power supplies, industrial power supplies, avionic power supplies, and portable instruments.
  • Input voltage range from 1.6V to 45V, power good flag
  • Single capacitor soft-starts reference and lowers output noise
  • Current limit foldback protection, reverse battery and thermal limit protection
  • Quiescent current in shutdown is 0.2µA typical at (VIN = 45V, active-low VSHDN = 0V, TA = 25°C)
  • Output voltage noise is 90µVRMS typical at (COUT = 10µF, ILOAD = 500mA, VOUT = 600mV, TA = 25°C)
  • Input reverse leakage current is 300µA max at (VIN = -45V, VOUT = 0)
  • Dropout voltage is 110mV typical at (ILOAD = 10mA, TA = 25°C)
  • Ripple rejection is 78dB typical at (VIN – VOUT = 2V, VRIPPLE = 0.5VP-P, TA = 25°C)
  • 1.2V regulated output voltage at (VIN = 2.2V, ILOAD = 1mA, TA = 25°C)
  • Operating temperature range from -40°C to 125°C, 10-lead plastic DFN package
