HL · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
7533 from HL, 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 | System ground pin; the reference for the VIN-GND absolute maximum of 30 V and the VOUT-GND absolute maximum of 15 V. |
| 2 | Vin | power_in | Regulator input pin, with an absolute maximum of 30 V (VIN-GND) and a stated input voltage range of 3 V to 24 V at no load. |
| 3 | Vout | power_out | Regulated output pin, nominally 3.3 V with ±2% output accuracy and a maximum output current of 150 mA; dropout is 800 mV typical-max at 150 mA. |
