HXY MOSFET · Linear Voltage Regulators (LDO) · TO-263-5L
MIC29302WU-HXY from HXY MOSFET, in a TO-263-5L. 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 | EN | input | Enable pin, compatible with CMOS logic levels: EN high turns the device on and EN low puts it in shutdown, where quiescent current is near zero; the datasheet gives EN limits of -0.3V to VIN (absolute maximum) and 0.8V low / 2.4V high thresholds. |
| 2 | IN | power_in | Input voltage pin; maximum continuous operating input voltage is 26V, and the absolute maximum input voltage range is -20V to +60V. |
| 3 | GND | power_in | Ground pin; the frame substrate is also connected to the device ground. |
| 4 | OUT | power_out | Regulated output pin; the output current is limited to 4.5A minimum and 5A typical at VOUT=0V, and the dropout is 370mV typical at 3A. |
| 5 | ADJ | input | Adjust feedback pin; it connects to a resistor divider between the output and ground to set the output voltage, with a bias current of 40 to 120 nA at the adjust pin. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
