Description
The IFX27001 is a monolithic integrated NPN type voltage regulator that can supply loads up to 1.0 A. 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 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 125 °C..

Note: Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are
not designed for continuous repetitive operation.

Application Hints
Adjustable Version
At the fixed voltage IFX27001 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:
VQ

IFX27001
Application Information
For the variable regulator IFX27001TFV, 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 IFX27001 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 series 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.
