MAX871EUK+T

Analog Devices Inc Maxim Integrated · Power Management - Specialized · SOT-23-5

MAX871EUK+T from Analog Devices Inc Maxim Integrated, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT power_out Inverting charge-pump output that approaches -5V when lightly loaded and droops toward GND as load current increases; OUT must not be pulled above ground under heavy sourced current, and OUT short-circuit to GND is indefinite.
2 IN power_in Positive power-supply input with a +1.4V to +5.5V operating range, and absolute maximum IN to GND of +6.0V.
3 C1- passive Flying capacitor negative terminal, with absolute range (VOUT - 0.3V) to +0.3V.
4 GND power_in Ground reference pin.
5 C1+ passive Flying capacitor positive terminal, with absolute range (VIN + 0.3V) to -0.3V.
