Product Description

The LD1117S12TR is a Low-drop Voltage Regulator with 1.2V output voltage and it is able to provide up to 800mA of output current, available even in adjustable version (VREF =1.25 V). 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 10µF 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 regulator is pin-to-pin compatible with the other standard. Adjustable voltage regulator maintains the better performances in terms of drop and tolerance.
Low dropout voltage (1V typical)
2.85V Device performances are suitable for SCSI-2 active termination
Internal current and thermal limit
75dB (typical) Supply voltage rejection
