Iout max = 300mA
Accuracy 3%
Low noise: 30 uVrms (10 Hz to 100 kHz)
Dropout 300mV at full load
Quiescent current 105 uA (no load)
Current limit max 475 mA
Thermal shutdown
Minimum capacitance required on output is 1uF (with less than
300mOhm ESR)
Current measurements via external tools can be done
either via this header or from the supply muxing
header (this header is kept for compatibility reasons
to the other Xplained Pro boards)
500mA low noise LDO voltage regulator
Noise: 40uVrms
Accuracy 2%
Dropout 200 mV at full load
Quiescent current 90 uA
Current limit 700 mA
Thermal shutdown
Minimum capacitance required on output is 2.2uF (with low ESR)
R104 and D100//R100 charges
C109 during power up without
turning the MOSFETs on. C109
and R100 will slow down the
turn-on time of the MOSFETs to
prevent any power surge.
Jumper for current
measurement.
Power input multiplexer priority:
1. VCC_EXT_IN
2. VCC_EDBG_USB
Voltage divider
footprint for
adjustable version.
Power inputs/ouputs to the Xplained PRO:
VCC_EXT_P5V0 (input)
This power input can be used to power the whole board and it has a
higher priority as the USB power input.
VCC_P5V0 (output)
This supply is connected to either VCC_EXT_P5V0 or
VCC_EDBG_USB_P5V0, based on the availability and priority of
these supplies.
VCC_TARGET_P3V3_P5V0 (output)
Target supply voltage (target MCU and peripherals)
Power input multiplexer priority:
1. VCC_EXT_IN
2. VCC_EDBG_USB
