ISL80101IRAJZ-T from RENESAS, in a TDFN-10-EP(3x3). 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 | power_out | Regulated output voltage; an X5R/X7R output capacitor is required for stability. |
| 2 | VOUT | power_out | Regulated output voltage; an X5R/X7R output capacitor is required for stability. |
| 3 | ADJ | input | Feedback input from the resistor divider that sets the output voltage (0.8V to 5V); the power-good circuit also uses this pin to monitor VOUT. |
| 4 | PG | output | Open-drain power-good output that goes low when VOUT is not in regulation; it can sink up to 10mA, should not be pulled up above VIN, and must be grounded if unused. |
| 5 | GND | power_in | Ground. |
| 6 | SS | passive | External capacitor on this pin sets the start-up ramp time and controls inrush current. |
| 7 | ENABLE | input | VIN-independent chip enable, TTL and CMOS compatible; it must not be left floating and should be tied to VIN if not used. |
| 8 | NC | unconnected | No connection; leave floating. |
| 9 | VIN | power_in | Input supply, 2.2V to 6V; a minimum of 10µF X5R/X7R input capacitor is required for proper operation. |
| 10 | VIN | power_in | Input supply, 2.2V to 6V; a minimum of 10µF X5R/X7R input capacitor is required for proper operation. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
