HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-5
MIC29302AWS from HGSEMI, in a TO-263-5. 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 input is active-high, CMOS compatible, must not float, and per the electrical characteristics has a logic low (OFF) threshold of 0.8V and a logic high (ON) threshold of 2.4V. |
| 2 | IN | power_in | Unregulated input, rated +3V to +16V maximum (operating input voltage 3V to 16V). |
| 3 | GND | power_in | Ground pin; the TAB is also connected internally to the IC's ground on both packages. |
| 4 | OUT | power_out | Regulator output voltage pin. |
| 5 | ADJ | input | Feedback voltage pin receiving the 1.24V feedback from the external resistor divider that sets the output voltage. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
