Output Current-Max: 1A
Package Style:  TO-252-3 (DPAK)
Mounting Method: Surface Mount
Features & Applications

The LD1117ADT12TR is a low drop positive voltage regulator with an output voltage of 1.2 V and an output current up to 1 A. It is available in surface mount TO-220-3 package.

High efficiency is assured by an NPN pass transistor. Only a very common 10 μF minimum capacitor is needed for stability. Chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±2% at 25 °C

Features:

  • Low dropout voltage:
    • 1.15 V typ. @ IOUT= 1 A, 25 °C
  • Very low quiescent current:
    • 5 mA typ. @ 25 °C
  • Output current up to 1 A
  • Fixed output voltage of:
    • 1.2 V, 1.8 V, 2.5 V, 3.3 V
  • Adjustable version availability (VREF= 1.25 V)
  • Internal current and thermal limit
  • Only 10 μF for stability
  • Available in ±2% (at 25 °C) and 4% in full temperature range
  • High supply voltage rejection:
    • 80 dB typ. (at 25 °C)
  • Temperature range: 0 °C to 125 °C
