Key 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: 3.3 V
  • Adjustable version availability (VREF= 1.25 V)

The LD1117 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, 3.3 V and 5.0 V. The device is supplied in: TO-220. 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. The adjustable LD1117 is pin to pin compatible with the other standard. Adjustable voltage regulators maintaining the better performances in terms of drop and tolerance.
