Description
The OPTIREG™ Linear TLE4264-2 is a monolithic integrated low-drop fixed voltage regulator which can supply
loads up to 150 mA. It is functional compatible to the TLE4264, but has a reduced quiescent current of typ.
40 µA. The TLE4264-2 is especially designed for all applications which require very low quiescent currents. The
device is available in the small surface mounted PG-SOT223-4 package. The device is pin compatible to the
TLE4264. The regulator 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 overtemperature. Of course the TLE4264-2 can be used in all other applications, wherever a stabilized
voltage is required.
An input voltage VI in the range of 5.5 V < VI < 45 V is regulated to VQ,nom = 5 V with an accuracy of ±3%. An
accuracy of ±2% is kept for a load current range up to 50 mA.
The device operates in the temperature range of Tj = -40°C to 150°C.

Application circuit
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, overtemperature and reverse polarity.
In the TLE4264-2 the output voltage is divided and compared to an internal reference of 2.5 V typical. The
regulation loop controls the output to achieve an output voltage of 5 V with an accuracy of ±3% at an input
voltage range of 5.5 V < VI < 45 V.
Figure 3 shows a typical application circuit. For stability of the control loop the TLE4264-2 output requires an
output capacitor CQ of at least 10 µF with a maximum permissible ESR of 4 Ω. Tantalum as well as multi layer
ceramic capacitors are suitable.
At the input of the regulator an input capacitor is necessary for compensating line influences (100 nF ceramic
capacitor recommended). A resistor of approx. 1 Ω in series with CI, can damp any oscillation occurring due
the input inductivity and the input capacitor.
In the application circuit shown in Figure 3 an additional electrolytic input capacitor of 470 µF 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 TLE4264-2 can supply up to 150 mA. However for protection for high input voltage above 25 V, the output
current is reduced (SOA protection).
