TPAP7343D-33FS4

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN1x1-4

TPAP7343D-33FS4 from TECH PUBLIC, in a DFN1x1-4. 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 (3.3V fixed for the -33 option, 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, 1.4V to 5.5V recommended operating range (absolute maximum -0.3V to 6.5V to GND).
5 GND power_in Center exposed pad labeled GND on the pin configuration drawing and not listed in the pin table.
