TP2028-1.8YN5G

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

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.
