Features
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
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 2.85 V type is ideal
for SCSI-2 lines active termination. 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
Table 1.
