Functional Description
The IFX 1117 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 IFX 1117 GSV33 supplies a regulated output voltage of 3.3 V (±2%). The
IFX 1117 GSV supplies an output voltage with ±2% precision adjustable via an external
voltage divider. The input voltage for the IFX 1117 GSV33 ranges from 4.5 V (= V_Q+V_DR)
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 V_DR ranges from 1.1 V to 1.4 V
depending on the load current level.
The device operates in the temperature range of T_j = 0 to 125 °C.
