The LD1117AS33TR is a low drop fixed and adjustable Positive Voltage Regulator with 3.3V output voltage and it is able to provide up to 1A of output current, available also in adjustable versions (VREF=1.25V). Surface mounted packages optimize the thermal characteristics while offering a relevant space saving advantage. High efficiency is assured by an NPN pass transistor. Only a very common 10μF minimum capacitor is needed for stability. Chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±2% at 25°C.
