TS4264GCW50 5V/150mA Fixed-Voltage Ultra Low LDO SOT-223 Pin Definition: 1. Input 2. Ground (tab) 3. Output General Description The TS4264GCW50 is a monolithic integrated low-drop fixed voltage regulator which can supply loads up to 150mA. It is functional compatible to the TS4264CW50 but has a reduced quiescent current of typ. 40A. The TS4264GCW50 is especially designed for all applications which require very low quiescent currents. This ULDO is designed to supply microprocessor systems under the severe condition of automotive applications and is therefore equipped with additional protection against overload, short-circuit and over temperature. Of course the TS4264GCW50 can be used in all other applications, wherever a stabilized voltage is required. An input voltage in the range of 5.5V ~ 45V is regulated to VOUT= 5V with an accuracy of 3%. An accuracy of 2% is kept for a load current range up to 50mA. The device operates in the temperature range of TJ = -40 ~150C. Features Fixed Output Voltage 5V Output Voltage Tolerance 3% 150mA Current Capability Ultra Low Quiescent Current 40A (Typ.)

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. 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 Typical Application Circuit Dimensioning Information on External Components The input capacitor CIN is necessary for compensating line influences. Using a resistor of approx. 1 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 10F and an ESR 4 within the operating temperature range. The application circuit shows additional electrolytic input capacitor of 470F 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). 3/5 Version: B14 TS4264GCW50 5V/150mA Fixed-Voltage Ultra Low LDO SOT-223 Mechanical Drawing Unit: Millimeters Marking Diagram Y M = Year Code = Month Code (A=Jan, B=Feb, C=Mar, D=Apl, E=May, F=Jun, G=Jul, H=Aug, I=Sep, J=Oct, K=Nov, L=Dec) = Month Code for Halogen Free Product (O=Jan, P=Feb, Q=Mar, R=Apl, S=May, T=Jun, U=Jul, V=Aug, W=Sep, X=Oct, Y=Nov, Z=Dec) L = Lot Code 50 = 5V Fixed Output Voltage 4/5 Version: B14 TS4264GCW50 5V/150mA Fixed-Voltage Ultra Low LDO Notice Specifications of the products displayed herein are subject to change without notice.
