FDC6330L from onsemi, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 R2 passive Source of internal N-channel control MOSFET Q1. Connected externally to ground through pull-down resistor R2 (typ. 1k-4.7 kΩ) which sets the slew rate of Q2's gate turn-on.
2 VOUT/C1 power_out Drain of internal P-channel power MOSFET Q2; switched output to the load. Tied to pin 3 (both are Q2 drain leads for current handling). Output bypass capacitor C1 (≤1 µF) connects here.
3 VOUT/C1 power_out Drain of internal P-channel power MOSFET Q2; switched output to the load. Tied to pin 2 (both are Q2 drain leads for current handling).
4 VIN/R1 power_in Source of P-channel power MOSFET Q2; connect to the input rail (3-20 V, up to 30 V with proper R1/R2 scaling). External pull-up resistor R1 ties this pin to pin 6 to keep Q2 off when ON/OFF is low.
5 ON/OFF input Gate of internal N-channel control MOSFET Q1. Logic-level enable input with a rated range of 1.5-8 V; drive high to turn the switch on, low to turn it off. Q1 includes Zener ESD protection (>6 kV HBM).
6 R1/C1_GATE passive Drain of control MOSFET Q1 and gate of power MOSFET Q2. External R1 connects this pin back to VIN (pin 4) to pull Q2's gate off; R1/R2 ratio is chosen in the range 10-100. Optional in-rush snub capacitor C1 (≤1000 pF) may be added here for slew-rate control.
