LD1117DT25TR

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.
