LM66100DCKT from Texas Instruments, in a SC-70-6. 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 | VIN | power_in | Device input; the recommended input voltage range is 1.5 V to 5.5 V, and the absolute maximum input voltage range is -6 V to 6 V. |
| 2 | GND | power_in | Device ground. |
| 3 | CE | input | Active-low chip enable that can be connected to VOUT for reverse current protection; do not leave floating, the recommended CE pin voltage range is 0 V to 5.5 V and the absolute maximum CE pin current is -1 mA. |
| 4 | N/C | unconnected | Not internally connected; can be tied to GND or left floating. |
| 5 | ST | output | Active-low open-drain status output that is pulled low when the chip is disabled and high-impedance when enabled; connect to GND if not required, with a recommended ST pin voltage range of 0 V to 5.5 V and an absolute maximum ST pin current of -1 mA. |
| 6 | VOUT | power_out | Device output; the recommended output voltage range is 1 V to 5.5 V. |
