LD1117S33CTR LDO Regulator Pos 3.3V 1.3A 4-Pin(3+Tab) SOT-223 T/R



General Description :

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: 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. 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.
