UR233
LINEAR INTEGRATED CIRCUIT
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 (VREF=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 10F
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.
