TS4264GCW50 RPG

P1-P3P4-P6
TS4264G
Taiwan Semiconductor
Document Number: DS_P0000204 1 Version: C15
Ultra Low Quiescent Current
5V/150mA Fixed-Voltage Ultra Low LDO
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.
Dimensioning Information on External Components
The input capacitor C
IN
is necessary for compensating line influences. Using a resistor of approx. 1 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 4
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).
