NAME FUNCTION 1 Input 2 Ground Ground 3 Output Block to ground with 10µF capacitor, ESR < 4Ω Block to ground directly on IC with ceramic capacitor APPLICATION INFORMATION In the TS4264GCW50 the output voltage is divided and compared to an internal reference of 2.5V typical. The regulation loop controls the output to achieve an output voltage of 5V with an accuracy of ±3% at an input voltage range of 5.5V~45V. Dimensioning Information on External Components The input capacitor CIN is necessary for compensating line influences. Using a resistor of approx. 1Ω in series with CIN, the oscillating of input inductivity and input capacitance can be clamped. The output capacitor COUT is necessary for the stability of the regulating circuit. Stability is guaranteed at values COUT ≥10µF and an ESR ≤ 4Ω within the operating temperature range. The application circuit shows additional electrolytic input capacitor of 470µF is added in order to buffer supply line influences. This capacitor is recommended, if the device is sourced via long supply lines of several meters. The TS4264GCW50 can supply up to 150mA. However for protection for high input voltage above 25V, the output current is reduced (SOA protection). Document Number: DS_P0000204 3 Version: C15 TS4264G Taiwan Semiconductor APPLICATION INFORMATION (CONTINUE) Circuit Description The control amplifier compares a reference voltage, which is kept highly precise by resistance adjustment, to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation control, working as a function of load current, prevents any over-saturation of the power element. The IC is additionally protected against overload, over temperature and reverse polarity Document Number: DS_P0000204 4 Version: C15 TS4264G Taiwan Semiconductor PACKAGE OUTLINE DIMENSIONS (Unit: Millimeters) SOT-223 SUGGESTED PAD LAYOUT (Unit: Millimeters) MARKING DIAGRAM Y = Year Code M = Month Code for Halogen Free Product O =Jan P =Feb Q =Mar R =Apr S =May T =Jun U =Jul V =Aug W =Sep X =Oct Y =Nov Z =Dec L = Lot Code (1~9, A~Z) 50 = 5V fixed Output Voltage Document Number: DS_P0000204 5 Version: C15 TS4264G Taiwan Semiconductor Notice Specifications of the products displayed herein are subject to change without notice.
