The chip is housed in a surface mounted PG-TO252-3-11 package (DPAK). It is designed to supply microprocessor systems or other loads under the severe conditions of automotive applications and therefore it is equipped with additional protection against overload, short circuit and overtemperature. An input voltage V in the range of (V + V ) < V < 40 V is regulated to V . The dropout I Q DR I Q voltage V ranges from 1.1 V to 1.4 V depending on the load current level. DR The device operates in the temperature range of T = -40 to 150 °C. j Type Package Marking TLE 4284 DV PG-TO252-3-11 4284V TLE 4284 DV15 PG-TO252-3-11 4284V15 TLE 4284 DV18 PG-TO252-3-11 4284V18 TLE 4284 DV26 PG-TO252-3-11 4284V26 TLE 4284 DV33 PG-TO252-3-11 4284V33 TLE 4284 DV50 PG-TO252-3-11 4284V50 Data Sheet 1 Rev. 2.1, 2007-03-20

TLE 4284 Application Hints Adjustable Version At 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, 2.6 V, 1.8V or 1.5V. The variable version compares the voltage difference between the adjust pin ADJ and the output pin Q to the internal reference of typically 1.25 V. The output voltage is adjusted by an external voltage divider between Q, ADJ and GND and calculates: R ×  2 × V = V 1 + ----- + I R Q REF   ADJ 2 R 1 For the variable regulator TLE 4284 DV, a minimum load current of 5 mA is necessary in order to keep the output voltage regulated. If the application does not assure this minimum load requirement, the output voltage divider should be dimensioned sufficiently low-ohmic: R ≤ 240 Ω. 1 For the variable voltage type an additional decoupling a capacitor C at the adjust pin ADJ improves the ripple rejection ratios. Placing C requires an increased output ADJ capacitance of C ≥ 22 µF. Q 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 a 10 µF output capacitor with 0.1 Ω ≤ ESR ≤ 10 Ω for the stability of the regulation loop. At the input of the regulator a capacitor is necessary for compensation of line influences. A serial diode should be used to eliminate negative voltages from the input. As a minimum, a 100 nF ceramic input capacitor should be used. If the regulator is used in an environment with long input lines, an input capacitance of 10 µF is recommended.
