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).

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.
