ME2135A50M6G from MICRONE, in a SOT-23-6. 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	VOUT	power_out	Regulated charge-pump output pin (5.0V nominal, ±3%). Bypass with a low-ESR ceramic capacitor (COUT ≥ 0.45uF, 10uF typical) to GND to minimize output ripple. Can source up to 300mA at VIN=3.6V.
2	GND	power_in	Ground reference pin for the device. Connect to the system ground plane.
3	EN	input	Enable input pin. Drive above VIN/2 to enable the converter; drive to 0V to place the device into shutdown (ISHDN ≈ 0uA). Absolute maximum voltage -0.3V to 6.0V.
4	C-	passive	Negative terminal of the flying (FLY) charge-pump capacitor. Connect a low-ESR ceramic CFLY (10uF typical) between C- (pin 4) and C+ (pin 6). Do not use polarized tantalum or aluminum electrolytic capacitors here.
5	VIN	power_in	Input supply pin, 2.7V-5.5V for the A50 (5.0V output) variant. Bypass with a 10uF low-ESR ceramic capacitor to GND. Absolute maximum voltage -0.3V to 6.0V.
6	C+	passive	Positive terminal of the flying (FLY) charge-pump capacitor. Connect a low-ESR ceramic CFLY (10uF typical) between C+ (pin 6) and C- (pin 4).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`me2135a50m6g.step`	97 KB	You want the bare part, or you mark your own boards.
`me2135a50m6g-etched.step`	2.4 MB	You want the part with `ME2135A50M6G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 577 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
