Voltage Regulator TLE 4284 Features • • • • • • • • • • Adjustable output voltage or 1.5V, 1.8V, 2.6V, 3.3 V, 5.0V output voltage 1.0 A output current Low dropout voltage, typ. 1 V Short circuit protection Overtemperature protection Wide operating range up to 40 V Wide temperature range of Tj = -40 to 150 °C Suitable for use in automotive electronics Green Product (RoHS compliant) AEC Qualified PG-TO-252-3 Functional Description The TLE 4284 is a monolithic integrated NPN type voltage regulator that can supply loads up to 1.0 A. 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 VI in the range of (VQ + VDR) < VI < 40 V is regulated to VQ. The dropout voltage VDR ranges from 1.1 V to 1.4 V depending on the load current level. The device operates in the temperature range of Tj = -40 to 150 °C.

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: VQ R2 = V REF × 1 + ----- + I ADJ × R 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: R1 ≤ 240 Ω. For the variable voltage type an additional decoupling a capacitor CADJ at the adjust pin improves the ripple rejection ratios. Placing CADJ requires an increased output capacitance of CQ ≥ 22 µF. 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.
