Product Overview

The LD1117V33 is a fixed output low dropout (LDO) positive voltage regulator in 3 pin TO-220 package. High efficiency is assured by NPN pass transistor. Unlike than PNP, the quiescent current flows into the load and 10μF minimum capacitor is needed for stability. Onchip trimming allows this regulator to reach very tight output voltage tolerance of ±1% at 25°C.
  • Fixed output voltage is 3.3V
  • Low dropout voltage is 1.1V at 800mA output current
  • Output current is 950mA
  • Operating input voltage is 15V
  • Internal current and thermal limit
  • Available in ±1% (at 25°C) and 2% tolerance at full temperature range
  • Supply voltage rejection is typically 75dB
  • Operating junction temperature range from 0°C to 125°C
