LD1117/A
LOW DROP FIXED AND
ADJUSTABLE POSITIVE
VOLTAGE REGULATORS
DESCRIPTION
The UTC LD1117/A is a low dropout, 3-terminals
positive voltage regulator designed to provide output current
up to 800mA/1A, even available in adjustable version
(Vref=1.25V). Regarding fixed versions, 1.5V, 1.8V, 2.5V,
2.85V, 3.0V, 3.3V, 3.6V and 5.0V are offered. The 2.85V
type is ideal for SCSI-2 lines active termination. Various
surface mount packages optimize the thermal characteristics
even offering a relevant space saving effect, including
SOT-223, TO-263, TO-252and SOP-8.
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. It allows very tight
output voltage tolerance within
±1%
at 25°C by chip trim.
Moreover, the ADJUSTABLE version is pin to pin compatible
with the other standard Adjustable voltage regulators
maintaining the better performances in terms of Drop and
Tolerance.
