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.

Description

The LD1117 is a low drop voltage regulator able

to provide up to 800 mA of output current,

available even in adjustable version (V

REF

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
