Power sources
=== Input Power sources ===
 
*'''VIN''' is the main voltage regulator that generates all the necessary internal voltages for IGEP COM AQUILA. VIN source needs 5V and 400 mA (typical value).
 
*'''VBACKUP''' is RTC backup power supply.
=== Output Power sources ===
 
*'''VOUT''' is a linear regulator that supply 3V3 / 1A
 
*'''VREFP_ADC''' is a supply voltage range for ADC.
 
=== Power sources design notes ===
 
* IGEP COM AQUILA uses a TPS73701, this LDO converts 5V (VIN input) to 3V3 (VOUT output), so you can use the following formula to calculate the maximum VIN current consumption: VIN (maximum supply current) = 550 mA + VOUT (maximum output current).
