LANKE · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L
LK7533-S from LANKE, in a SOT-23-3L. 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 reference pin of the LK75XX regulator, labelled VSS in the SOT23-3 top-view diagram. The datasheet gives no further electrical limit for this pin. |
| 2 | VOUT | power_out | Regulated 3.3V output (VOUT 3.234V to 3.366V at VIN=5.3V, IOUT=10mA) rated for up to 150mA, with C2 recommended at 1-10uF. |
| 3 | VIN | power_in | Input supply pin with a maximum input voltage of 30V in the electrical table (36V absolute maximum), with C1 recommended at 1-10uF. |
