Features & Applications
The LD1117S25CTR is a low drop fixed positive voltage regulator with an output voltage of 2.5 V and an output current up to 1300 mA. It is available in surface mount SOT-223-3 package. The 2.85 V type is ideal for SCSI-2 lines active termination.

High efficiency is assured by an NPN pass transistor, in this case, unlike than PNP one, the quiescent current flows mostly into the load. 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 ±1 % at 25 °C.

Features:

  • Low dropout voltage (1 V typ.)
  • 2.85 V device performances are suitable for SCSI-2 active termination
  • Output current up to 800 mA
  • Fixed output voltage of: 1.2 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V
  • Adjustable version availability (VREF= 1.25 V)
  • Internal current and thermal limit
  • Available in ±1 % (at 25 °C) and 2 % in full temperature range
  • Supply voltage rejection: 75 dB (typ.)
