Torex Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25-5
XC6901D501MR-G from Torex Semicon, in a SOT-25-5. 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 | GND | power_in | Ground reference pin; all absolute maximum ratings and electrical characteristics are specified with GND = 0V. |
| 2 | -VIN | power_in | Negative supply input; the datasheet gives an input range of -2.4V to -12.4V (VCE = 3.6V) and an absolute maximum range of GND-18+VCE to GND+0.3V. |
| 3 | CE | input | ON/OFF control, active high: a level of 1.2V to 3.6V enables the regulator, GND to 0.4V puts it in stand-by, and an open pin also gives stand-by due to the internal pull-down; the absolute maximum CE voltage is GND-0.3V to VIN+18V. |
| 4 | NC | unconnected | No connection. |
| 5 | -VOUT | power_out | Negative regulated output (-5.0V nominal for this -5.0V part) with a maximum output current of 200mA; the absolute maximum output voltage range is -VIN-0.3V to GND+0.3V. |
