TPMIC5233-5.0YM5 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	Input supply voltage pin. Operating range 2V to 36V (recommended 3.5V to 36V). Bypass with a 1µF ceramic capacitor to GND. Absolute maximum -0.3V to 40V.
2	GND	power_in	Device ground reference. Ground quiescent current is typically 2µA at no load (VOUT ≤ 5V).
3	EN	input	Enable control input. Drive high (VIH ≥ 2V) to enable the regulator; drive low (VIL ≤ 0.6V) to shut down. Input current typically 10nA at VEN=36V. Shutdown ground current is 0.01µA (typ).
4	NC	unconnected	No internal connection. May be left floating or tied to a convenient node.
5	VOUT	power_out	Regulator output. Fixed 5.0V output (this variant), ±2% accuracy, 200mA continuous output current with 300mA typ current limit. Requires a ≥1µF effective capacitance ceramic output capacitor for stability. Dropout typically 0.66V at 100mA load.
