UNISONIC TECHNOLOGIES CO., LTD UC621XX BOOSTING VOLTAGE REGULATORS DESCRIPTION The UTC UC621XX is a positive output voltage regulator that can supply up to 1A of output current using an external transistor. Low power and high accuracy are achieved through CMOS process and metal fuses trimming technologies. The series consists of a high precision voltage reference, an error correction circuit and a short-circuit protected output driver. In stand-by mode, supply current can be dramatically cut. Since the input-output voltage differential is small, loss control efficiency is good. The UTC UC621XX is particularly suited for use with battery operated portable products, and products where supply current regulation is required. 3 2 1 CMOS IC 5 4 SOT-25 *Pb-free plating product number: UC621XXL FEATURES * Ultra Small Input-Output Voltage Differential : 100mA of output current is available with a differential of 0.1V.

CIN :10 F(Tantalum) C L: 47F(Tantalum)10F minimum OPERATIONAL EXPLANATION Functional Description Output voltage (VOUT) can be fixed by revising the external transistor's base current. This can be done by comparing the detected voltage level and the set voltage power supply level. DIRECTIONS FOR USE Suggestions for External Comporients 1. PNP Transistor The selection of a transistor should take into account output current, input voltage and power dissipation for each specific application. It is recommended that a transistor that has a low output saturated voltage (VCE) and high hFE characteristics be used. 2. RB Resistor Although the IC unit is protected by a base current remitter circuit, it is recommended that a resistor (RB) be connected between the transistor's base and the IC's EXT pin to protect the transistor. Required output current can be calculated using the following equation although characteristic variations and conditions of use should be carefully checked before use. The following equation also indicates the conditions needed to obtain IOUT (max.) at VIN (min.). However, the larger the input current, the larger the output current (IOUT) that can be obtained. VIN(min) -1.2(V) RB 0.7(V) RBE IOUT(max) hFE 3. RBE Resistor, CL Capacitor To prevent oscillation due to output load variation, use of a phase compensation capacitor CL is recommended. Please use a Tantalum capacitor of at least 10F. Please also use an RBE resistor of less than 47k. An RBE resistor of between 20k and 47k is recommended for less power consumption. 4. Input Impedance In order to control oscillation brought about as a result of impedance at the power supply line, connect a capacitor of 10F or more (Tantalum) between the external transistor's emitter and the ground pin. Special Note 1. Protection Circuit The built-in protect circuit is to protect the IC only. Therefore to prevent output shorts and overshoot current through the transistor, use of a resistor RB or an overshoot current protection circuit is recommended. Care should also be taken with the transistor's power dissipation.
