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 F tantalum capacitor is required at the output.
