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). Concerning fixed versions,
are offered the following Output Voltages: 1.8V, 2.5V, 2.85V,
3.0V, 3.3V and 5.0V. The device is supplied in: SOT-223,
SOT-89,TO-252, TO-263, TO-263-3, SOP-8 and TO-220. The
SOT-223,SOT-89,SOP-8,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 10
F 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 UR233 is pin to pin compatible with the other
standard Adjustable voltage regulators maintaining the better
performances in terms of Drop and Tolerance.
