AT6211C28SEG-N from Agertech, 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 | VIN | power_in | Power input; operating voltage range is 1.2V to 6.0V (absolute maximum 6.5V). |
| 2 | VSS | power_in | Ground. |
| 3 | CE | input | ON/OFF control; CE high of at least 1.0V starts up the output and CE low of at most 0.5V shuts it down (standby current 0.1uA typ.), with voltage limited to Vss-0.3V to VIN+0.3V. |
| 4 | NC | unconnected | No connect. |
| 5 | VOUT | power_out | Regulated output, 2.8V for the C28 version, with 450mA maximum output current and a 1uF output capacitor. |
