REGULATORS
DESCRIPTION
The UTC LD1117/A is a LOW DROP Voltage Regulator
able to provide up to 0.8/1.0A of Output Current, available
even in adjustable version (Vref=1.25V). Concerning fixed
versions, are offered the following Output Voltages: 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, TO-252, TO-263, TO-263-3, SOP-8 and TO-220.
The SOT-223, TO-263, TO-263-3 and TO-252 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 the 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/A is pin to pin compatible with the other standard
Adjustable voltage regulators maintaining the better
performances in terms of Drop and Tolerance.
