Description
The TLE42764 is a monolithic integrated low dropout voltage regulator
for load currents up to 400 mA. An input voltage up to 40 V is regulated
to an adjustable or 5 V fixed voltage with a precision of ±2%. The device
is designed for the harsh environment of automotive applications.
Therefore it is protected against overload, short circuit and
overtemperature conditions by the implemented output current limitation
and the overtemperature shutdown circuit. The TLE42764 can be also
used in all other applications requiring a stabilized voltage between 2.5 V
and 20 V.
PG-TO252-5
Due to its very low quiescent current the TLE42764 is dedicated for use
in applications permanently connected to VBAT. In addition the device can
be switched off via the Enable input reducing the current consumption to
less than 10 μA.

Electrical Characteristics Enable Function
The Enable Function allows disabling/enabling the regulator via the input pin EN. The regulator is turned on in
case the pin EN is connected to a voltage higher than VEN,H. This can be e.g. the battery voltage, whereby no
additional pull-up resistor is needed. The regulator can be turned off by connecting the pin EN to a voltage less
than VEN,L, e.g. GND.

Application Diagram
A typical application circuit of the TLE42764 is shown in Figure 4. It shows a generic configuration of the voltage
regulator, with the recommendable minimum number of components one should use. Theoretically, if there is no
risk of high frequency noise at all, even the small input filter capacitor can be omitted. For a normal operation mode
of the device the only required device is the output capacitor, for the TLE42764GV and the TLE42764DV
additionally the resistor divider. However, depending on the application’s environment, additional components like
an input buffer capacitor or a reverse polarity protection diode can be considered as well.
Input Filter Capacitor
A small ceramic capacitor (e.g. 100nF in Figure 4) at the device’s input helps filtering high frequency noise. To
reach the best filter effect, this capacitor should be placed as close as possible to the device’s input pin. The input
filter capacitor does not have an influence on the stability of the device’s regulation loop.
Output Capacitor CQ
The output capacitor is the only external component that is required in any case as it is a part of the device’s
regulating loop. To maintain stability of this loop, the TLE42764 requires an output capacitor respecting the values
given in “Functional Range” on Page 7.
Adjusting the Output Voltage of Variable Output Regulators TLE42764GV, TLE42764DV
The output voltage of the TLE42764GV and the TLE42764DV can be adjusted between 2.5 V and 20 V by an
external resistor divider, connected to the voltage adjust pin VA.
The pin VA is connected to the error amplifier comparing the voltage at this pin with the internal reference voltage
of typically 2.5 V.

External Components at Output for Variable Voltage Regulator
The output voltage can be easily calculated, neglecting the current flowing into the VA pin:
R1 + R2
V Q = ------------------- × V ref
R2
where
R 2 < 50 kΩ
to neglect the current flowing into the VA pin,
with:
•
•
•
Vref: internal reference voltage, typically 2.5V
R1: resistor between regulator output Q and voltage adjust pin VA
R2: resistor between voltage adjust pin VA and GND
For a 2.5 V output voltage the output pin Q has to be directly connected to the adjust pin VA.
Take into consideration, that the accuracy of the resistors R1 and R2 adds an additional error to the output voltage
tolerance.
