TP2028-1.8YN5G from TECH PUBLIC, in a SOT-23-5. 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 | VIN | power_in | Supply power input. Absolute maximum 7V; typical operation Vout+1V to 8V. Bypass to GND with a 1uF ceramic capacitor (CIN) placed close to the pin. |
| 2 | GND | power_in | Device ground reference. Connect to the system ground plane; also serves as the return for CIN and COUT. |
| 3 | CE | input | Chip Enable (active-high). Drive above VCE (1.1V typ) to enable the regulator; drive to 0V to place the device in shutdown mode (ICEL <1uA typ). Do not leave floating; tie to VIN if the enable function is not used. |
| 4 | NC | unconnected | No internal connection. May be left floating or tied to GND for improved mechanical stability. |
| 5 | VOUT | power_out | Regulated voltage output, factory-set to 1.8V (±2% tolerance) for the -1.8 variant. Rated for 500mA typical (600mA absolute max). Requires a 1uF ceramic output capacitor (COUT) close to the pin for stability. |
