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. 40µA. 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 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
IN
is 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
OUT
is
necessary for the stability of the regulating circuit. Stability is guaranteed at values C
OUT
≥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).
