MD7033 from Shanghai Mingda Microelectronics, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | output | Active-low NMOS open-drain detector output that goes low when VDD falls below the 3.3V detect voltage, sinking at least 2 mA at VOUT=0.2V (VDD=3.1V), with output current limited to 10mA and output voltage to VSS-0.3V to VDD+0.3V. |
| 2 | VDD | power_in | Positive supply input and monitored voltage, with an operating range of 1.5V to 15V and an absolute maximum of -0.3V to 18V. |
| 3 | GND | power_in | Ground reference (VSS) for the detector. |
| 4 | NC | unconnected | No-connect pin, labeled NC on the SOT23-5 pin assignment drawing. |
| 5 | NC | unconnected | No-connect pin, labeled NC on the SOT23-5 pin assignment drawing. |
