Functional Description

The TLE 4296 G is a monolithic integrated low drop voltage regulator in the very small
SMD package P-SCT595-5. It is designed to supply e.g. microprocessor systems under
the severe conditions of automotive applications. Therefore the device is equipped with
additional protection functions against overload, short circuit and reverse polarity. At
overtemperature the regulator is automatically turned off by the integrated thermal
protection circuit.

Input voltages up to 40 V are regulated to

V

Q,nom

= 3.0 V (V30 version) 3.3 V (V33
version) or 5.0 V (V50 version). The output is able to drive a load of more than 30 mA
while it regulates the output voltage within a 4% accuracy.

To save energy the device can be switched in stand-by mode via an inhibit input which
causes the current consumption to drop below 5

µA.

Figure 3 Application Circuit

Application Information

In the TLE 4296 G the output voltage is divided and compared to an internal reference
of 2.5 V typical. The regulation loop controls the output to achieve a stabilized output
voltage.

Figure 3 shows a typical application circuit. In order to maintain the stability of the control

loop the TLE 4296 G output requires an output capacitor
ESR of max. 10

µF / 16V B45196P3335M209 or 4.7 µF / 10 V B45196-P2475M109) or a multi layer

3.3

Ω and min. 3 Ω. It is recommended to use tantalum (e.g. the EPCOS

C

of at least 2.2 µF with an

Q

ceramic capacitor with a series resistor in order to cover these limits over the full
operating temperature range of -40

°C to 150 °C.

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

C

with

, can damp any oscillation occurring due the input inductivity and the input

capacitor.
