LM66100QDCKRQ1 from Texas Instruments, in a SC-70-6. 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 | VIN | power_in | Device input; operating voltage range 1.5V to 5.5V with input protection against -6V absolute maximum reverse polarity. |
| 2 | GND | power_in | Device ground reference. |
| 3 | CE | input | Active-low chip enable; MOSFET disables when VCE exceeds VIN by 80 mV and enables when VCE is 250 mV below VIN; do not leave floating. |
| 4 | N/C | unconnected | Not internally connected; can be tied to GND or left floating. |
| 5 | ST | tri_state | Active-low open-drain status output; pulled low when chip is disabled and high-impedance when enabled; connect to GND if not required. |
| 6 | VOUT | output | Device output; supports maximum continuous current of 1.5A with on-resistance 79 mΩ at 5V VIN typical. |
