UNISONIC TECHNOLOGIES CO., LTD 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 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. *Pb-free plating product number: UR233L 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) ORDERING INFORMATION Ordering Number Normal Lead Free Plating UR233-xx-AA3-①-② UR233L-xx-AA3-①-② UR233-xx-AB3-①-② UR233L-xx-AB3-①-② UR233-xx-TA3-①-② UR233L-xx-TA3-①-② UR233-xx-TN3-①-② UR233L-xx-TN3-①-② UR233-xx-TQ2-①-② UR233L-xx-TQ2-①-② UR233-xx-TQ3-①-② UR233L-xx-TQ3-①-② UR233-xx-S08-①-② UR233L-xx-S08-①-② Note: Pin Assignment: I:VIN O:VOUT G:GND Package SOT-223 SOT-89 TO-220 TO-252 TO-263 TO-263-3 SOP-8 ① Pin Assignment A: GOI B: OGI C: GIO D: IGO ② Packing R: Tape Reel T: Tube GOOIxOOx ORDERING INFORMATION(Cont.) www.unisonic.com.tw Copyright © 2008 Unisonic Technologies Co., Ltd 1 of 10 QW-R102-011.D UR233 LINEAR INTEGRATED CIRCUIT MARKING INFORMATION PACKAGE VOLTAGE PIN CODE PIN 1 CODE SOT-223 SOT-89 TO-220 TO-252 TO-263 TO-263-3 17:1.7V 18:1.8V 25:2.5V 2J:2.85V 30:3.0V 33:3.3V 50:5.0V AD:ADJ PIN 2 PIN 3 A GND OUT IN B OUT GND IN C GND IN OUT D IN GND OUT A GND OUT IN B OUT GND IN C GND IN OUT D IN GND OUT A GND OUT IN B OUT GND IN C GND IN OUT D IN GND OUT UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw MARKING 2 of 10 QW-R102-011.D UR233 LINEAR INTEGRATED CIRCUIT BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 10 QW-R102-011.D UR233 LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL VIN VALUE UNIT 12 V SOT-223 0.740 SOT-89 0.571 SOP-8 0.625 Power Dissipation PD W TO-252 1.471 TO-220 1.820 TO-263 2.222 Operating Junction Temperature TOPR -40 ~ +85 °С Storage Temperature TSTG -65 ~ +150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
