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.

TO-252

TO-263-3

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.
