UTC 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). 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 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°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.
