Features & Applications
The LD1117V33R is a low drop voltage regulator able to provide up to 800 mA of output current, available even in adjustable version (VREF = 1.25 V). Concerning fixed versions, are offered the following output voltages: 1.2 V, 1.8 V, 2.5 V, 2.85 V, 3.0 V, 3.3 V and 5.0 V. The 2.85 V type is ideal for SCSI-2 lines active termination. The device is supplied in: SOT-223, DPAK, SO-8 and TO-220.

The SOT-223 and DPAK surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. High efficiency is assured by NPN pass transistor. In fact 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. On 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, 3.0 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.)
