The chip is housed in a surface mount PG-TO252-3 package (DPAK). It is designed to supply microprocessor systems or other loads under the severe conditions and therefore it is equipped with additional protection against overload, short circuit and overtemperature. An large input voltage V in the range of (V + V ) < V < 40 V is regulated to V . The dropout voltage V ranges I Q DR I Q DR from 1.1 V to 1.4 V depending on the load current level. The device operates in the temperature range of T = -40 to 125 °C.. j Type Package Marking IFX27001TFV15 PG-TO252-3 2700115 IFX27001TFV18 PG-TO252-3 2700118 IFX27001TFV26 PG-TO252-3 2700126 IFX27001TFV33 PG-TO252-3 2700133 IFX27001TFV50 PG-TO252-3 2700150 IFX27001TFV PG-TO252-3 27001V Data Sheet 2 Rev. 1.01, 2009-10-19

The regulation loop controls the output voltage to achieve the output voltage of 5V, 3.3V, 2.6V, 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 1.25V. The output voltage is adjusted by an external voltage divider between Q, ADJ and GND and calculates: R V = V ×⎛1+ ----2-⎞ +I ×R Q REF ⎝ R ⎠ ADJ 2 1 Data Sheet 16 Rev. 1.01, 2009-10-19

IFX27001 Application Information For the variable regulator IFX27001TFV, a minimum load current of 5mA 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 improves the ripple ADJ rejection ratios. Placing C requires an increased output capacitance of C ≥22 µF. ADJ Q Output The output current limitation is reduced as a function of the input voltage for high input voltages above 25V. The IFX27001 requires a 10µF output capacitor with 0.1Ω ≤ ESR ≤ 10Ω for the stability of the regulation loop. At the input of the regulator a capacitor is necessary for compensation of line influences. A series diode should be used to eliminate negative voltages from the input. As a minimum, a 100nF ceramic input capacitor should be used. If the regulator is used in an environment with long input lines, an input capacitance of 10µF is recommended.
