TP2028-3.3YN5G

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

TP2028-3.3YN5G 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. Accepts up to 7V absolute max; requires Vout+1V for regulation. Bypass with a 1uF ceramic capacitor to GND close to the pin.
2 GND power_in Device ground reference. Connect to system ground plane.
3 CE input Chip Enable (active-high). Drive above VCE (min 1.1V) to enable the regulator; pull to GND (Vce = 0V) to place the device in shutdown mode where standby current ICEL is typically 1uA. Do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to a convenient net for PCB routing.
5 VOUT power_out Regulated voltage output, fixed at 3.3V (±2%) for the -3.3 option. Delivers up to 500mA typical (600mA absolute max). Requires a 1uF ceramic output capacitor to GND for stability.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: TECH PUBLIC datasheet (5 pp, sha256 858d45799d9d37d0, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
