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.
