The LD1117A is a low drop voltage regulator able to provide up to 1 A 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 and 3.3 V. The device is supplied in: SOT-223, DPAK, DPAK/A and TO-220. Surface mount packages optimize the thermal characteristics even offering a relevant space saving effect. High efficiency is assured by NPN pass transistor. Only a very common 10 F minimum capacitor is needed for
