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 10

μF

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.

FEATURES

*Low dropout voltage (1.5V Typ.)

*Output current up to 0.8A

*Fixed output voltage of: 1.7V,1.8V,2.5V, 2,85V, 3.0V, 3.3V, 5.0V

*Adjustable version availability (VREF=1.25V)

*Internal current and thermal limit

*Available in

±1%(at 25°С) and 2% in all temperature range

*Supply voltage rejection: 75dB (TYP)

*Pb-free plating product number: UR233L
