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 TS4264GCW50 but has a reduced quiescent current of typ. 40µA. The

TS4264GCW50 is especially designed for all applications which are 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 V_OUT= 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 T_J= –40 ~150°C.

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.

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 C_INis necessary for compensating line influences. Using a resistor of approx. 1Ω in series with C_IN,

the oscillating of input inductivity and input capacitance can be clamped. The output capacitor C_OUTis necessary for the

stability of the regulating circuit. Stability is guaranteed at values C_OUT≥10uF and an ESR ≤ 4Ω within the operating

temperature range.

The application circuit shows additional electrolytic input capacitor of 470uF 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).
