DESCRIPTION
The LD1117 is a LOW DROP Voltage Regulator
able to provide up to 800mA of Output Current,
available even in adjustable version (Vref=1.25V).
Concerning fixed versions, are offered the
following Output Voltages: 1.2V,1.8V,2.5V,2.85V,
3.0V 3.3V and 5.0V. The 2.85V type is ideal for
SCSI-2 lines active termination. The device is
supplied in: SOT-223, DPAK, SO-8, TO-220 and
TO-220FM. The SOT-223 and DPAK surface
mount
packages
optimize
characteristics even offering a relevant space
saving effect. High efficiency is assured by NPN
the
thermal
pass transistor. In fact in this case, unlike than
PNP one, the Quiescent Current flows mostly into
the load. Only a very common 10μF 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.
