MD88R36 from Shanghai Mingda Microelectronics, in a SOT-23-5L. 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 CE input Chip enable input. Drive high (V_CEH >= 0.9 V) to enable the converter; drive low (V_CEL <= 0.6 V, tie to GND) to place the device in shutdown (I_SHDN <= 0.5 uA typ 0.1 uA). Absolute max V_CE = Vss-0.3 to Vout+0.3 V.
2 VOUT power_in Regulated boost output-voltage sense pin; also supplies the internal control circuitry from the boosted rail. Nominal 3.6 V for MD88R36 with +/-2.5% accuracy. Absolute max Vss-0.3 V to Vss+12 V. Connect the output capacitor (>=100 uF tantalum recommended) and Schottky-diode cathode here.
3 NC unconnected No internal connection. Leave floating or tie to any convenient net; not electrically bonded inside the package.
4 VSS power_in Device ground / negative supply return (GND, 接地引脚). Reference for CE, VOUT, and LX voltages.
5 LX output Internal power-switch drain (boost switching node, 开关引脚). Connect the boost inductor (typ 27 uH, <0.5 ohm ESR) between VIN and LX and the Schottky diode (e.g. 1N5817) anode to LX. Absolute max V_LX = Vss-0.3 to Vss+12 V, I_LX <= 1000 mA; R_SWON ~0.4 ohm typ.
