ASPL7550DI-R
ASDsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
ASPL7550DI-R from ASDsemi, in a SOT-89-3. 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 | GND | power_in | Ground pin; left pin in the SOT-89 front view, pin 1 in the pin table. |
| 2 | VIN | power_in | Input supply pin; the datasheet gives a 24V maximum input voltage (-0.3V to +28V absolute maximum), with a 10uF capacitor recommended close to the pin. |
| 3 | VOUT | power_out | Regulated 5.0V output (ASPL7550) rated for 150mA typical; needs an output capacitor of at least 2.2uF to ground, with 10uF recommended. |
