Functional Description
The TLE 4284 is a monolithic integrated fixed or adjustable NPN type voltage regulator
that can supply loads up to 800 mA. The device is housed in the surface mounted
P-TO252-3-1 package (D-Pak). It is designed to supply microprocessor systems under
the severe conditions of automotive applications and therefore it is equipped with
additional protection against over load, short circuit and overtemperature.
An input voltage VI in the range of (VQ + 2 V) < VI < 45 V is regulated to VQ.
The device operates in the temperature range of Tj = – 40 to 150 °C.
The device is available for adjustable output voltage as well as in fixed voltage versions
for 3.3 V and 5.0 V (2.5 V on demand).

TLE 4284
In the fixed voltage TLE 4284 devices the output voltage is divided internally and
compared to an internal reference of 1.25 V typical. The regulation loop controls the
output voltage to achieve the output voltage of 5 V, 3.3 V or 2.5 V. The variable device
compares the voltage difference between the adjust pin ADJ and the output pin Q to the
internal reference of 1.25 V; the output voltage is adjusted by an external voltage divider
between Q, ADJ and GND (see equation in Figure 7).
Output
The output current limitation is reduced as a function of the input voltage for high input
voltages above 25 V.
The TLE 4284 requires no output capacitor for stability, however we recommend to use
a ceramic capacitor to filter any noise and improve the transient response.
At the input of the regulator a capacitor is necessary for compensation of line influences.
A resistor of approx. 1 Ω in series with CI can damp the LC of the input inductivity and
the input capacitor. A serial diode should be used to eliminate negative voltages from the
input.
For the variable voltage type an additional decoupling a capacitor CADJ at the adjust pin
can improve the ripple rejection ratios.
