HANSCHIP semiconductor · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
HX7133-1DBZRG from HANSCHIP semiconductor, in a SOT-23-3. 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 of the LDO; the datasheet lists it only as the ground reference (地) and gives no separate limit for this pin. Absolute ratings on page 3 apply to the device as a whole. |
| 2 | VIN | power_in | Input supply pin, rated at -0.3 V to +30 V absolute maximum, with the specified output requiring VIN = VOUT + 2 V (Vo + 1 V minimum for line regulation). |
| 3 | VOUT | power_out | Regulated output pin for the 3.3 V version (7133-1), rated 70 mA minimum and 100 mA typical output current, and requiring an output capacitor greater than 2.2 µF to ground for stability. |
