Functional Description The IFX1117 is a monolithic integrated fixed NPN type voltage regulator that can supply loads up to 1.0 A. The device is housed in the small surface mounted SOT223 package. The IC is equipped with additional protection against overload, short circuit and overtemperature. The IFX1117ME V33 supplies a regulated output voltage of 3.3 V (±2%). The IFX1117ME V supplies an output voltage with ±2% precision adjustable via an external voltage divider. The input voltage for the IFX1117ME V33 ranges from 4.5 V (= VQ+VDR) to 15 V for a load current of 800 mA, for the maximum load current of 1.0 A a minimum input voltage of 4.7 V is required. The drop 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 = 0 to 125 °C.

The use of a tantalum output capacitor is recommended. For the adjustable device IFX1117ME V the output voltage level can be defined by a voltage divider between Q, ADJ and GND. The output voltage calculates: R V Q = V REF × ⎛⎝ 1 + -----2-⎞⎠ + I ADJ × R 2 R1 (1) At the input of the regulator a capacitor is recommended to compensate line influences. 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 suggested.
