TP73318PDQNR

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4-EP(1x1)

TP73318PDQNR from TECH PUBLIC, in a DFN-4-EP(1x1). 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 VOUT power_out Regulated output voltage pin (fixed 0.8V to 3.45V options, up to 300mA output current).
2 GND power_in Ground.
3 EN input Enable input, active high, must not be left floating.
4 VIN power_in Input supply voltage, 1.4V to 5.5V operating range (absolute maximum -0.3V to 6.5V).
5 GND power_in Exposed thermal pad, labelled GND in the pin diagram.
