LR7525-T from LR, in a SOT-23-3. 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 | VSS | power_in | Ground pin (labelled VSS in the SOT23-3L pin drawing, GND in the block diagram), the common return for input and output. |
| 2 | VOUT | power_out | Regulated 2.5V output (±2% at VIN=VOUT+2V, IOUT=10mA) delivering 100mA typical, with a 1-10uF output capacitor recommended. |
| 3 | VIN | power_in | Input supply pin accepting up to 24V operating (32V absolute maximum), with a bypass capacitor of 1-10uF recommended close to the pin. |
