UR233
LOW DROP FIXED AND
ADJUSTABLE POSITIVE
VOLTAGE REGULATORS
DESCRIPTION
The UTC
UR233
is a LOW DROP Voltage Regulator able to
provide up to 0.8A of Output Current, available even in adjustable
version (V
REF
=1.25V).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°С. The ADJUSTABLE
UR233
is pin to pin
compatible with the other standard Adjustable voltage regulators
maintaining the better performances in terms of Drop and
Tolerance.
LINEAR INTEGRATED CIRCUIT
