AP2000ATCER from Wuxi Chipown Micro electronics, in a SOT-23-6L. 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 | SW | output | Switch pin for the external inductor, driven by the internal NMOS main switch and PMOS synchronous rectifier, with an absolute maximum rating of -0.3 V to +6 V. |
| 2 | GND | power_in | Power ground, which must be tied closely to VIN through a ceramic capacitor of 10 µF or greater. |
| 3 | FB | input | Feedback input connected to the center point of the external resistor divider, with a feedback threshold of 1.23 V and an absolute maximum rating of -0.3 V to +6 V. |
| 4 | SHDN | input | Shutdown control input where logic high gives normal operation and logic low gives shutdown, normally connected to VIN through a 1 MΩ resistor, with a 0.35 V to 1.50 V input threshold (0.60 V typical). |
| 5 | VOUT | power_out | Power output pin for the 2.5 V to 5.0 V regulated output, which sits 0.6 V below VIN while in shutdown, with an absolute maximum rating of -0.3 V to +6 V. |
| 6 | VIN | power_in | Power supply input that must be closely coupled to GND (pin 2) through a ceramic capacitor of 10 µF or greater, with an absolute maximum rating of -0.3 V to +6 V. |
