MST · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23
MST5633BTE from MST, in a SOT-23. 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 pin; the datasheet rates VIN to GND at -0.3 V to 80 V and VOUT to GND at -0.3 V to 6 V, and calls for wide copper traces on both VIN and GND. |
| 2 | VOUT | power_out | Regulated output pin, rated VOUT to GND at -0.3 V to 6 V and VOUT to VIN at -35 V to 0.3 V, with at least 1 µF ceramic (X7R or X5R) output capacitance placed as close as possible to VOUT and GND. |
| 3 | VIN | power_in | Input supply pin, rated VIN to GND at -0.3 V to 80 V, with a 5 V to 60 V operating input range and a 1 µF ceramic input capacitor recommended as close to the device as possible. |
