General Description
The IFX8117 is a family of low dropout voltage regulators with a dropout voltage of 1.2 V at 1 A of load current. It
is available as adjustable version (IFX8117MEV), providing output voltages from 1.25 V to 13.8 V, configured by
two external resistors. Additionally, the IFX8117 is also available in two fixed voltages, 5 V (IFX8117MEV50) and
3.3 V (IFX8117MEV33).
The IFX8117 implements protection features such as output current limitation and overtemperature shutdown. A
highly precise bandgap reference trimmed in production assures output voltage accuracy to within ±1%.
The IFX8117 family comes in the PG-SOT223-4 package. To improve the transient response and the stability, a
minimum of 10 µF tantalum capacitor is required at the output.
