TP2019-3.0YC5 from TECH PUBLIC, in a SC-70-5. 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	IN	power_in	Regulator input supply. Accepts 2.5V to 5.5V. Bypass to GND with a 1uF capacitor for stable operation.
2	GND	power_in	Ground reference for the regulator.
3	EN	input	Active-high shutdown/enable input. VIH >= 1.5V enables the regulator; VIL <= 0.3V drops supply current to ~10nA. Tie to IN for always-on operation. Absolute max: -0.3V to VIN.
4	BP	passive	Reference-noise bypass pin (fixed-voltage version, applies to TP2019-3.0YC5). Connect a low-leakage 0.01uF ceramic capacitor from BP to GND to reduce output noise to ~30uVRMS. On adjustable versions this pin functions as FB (voltage-divider feedback) instead.
5	OUT	power_out	Regulated 3.0V output. Delivers up to 150mA (250mA for VOUT>2V) in SC70-5 package. Requires 1uF ceramic output capacitor for stability.
