GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
GR7533HS from GR, 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 | Chip ground terminal; the datasheet gives no separate limit for this pin. |
| 2 | VOUT | power_out | Chip regulated output terminal; for GR7533H the output is 3.3 V (±3%, 3.201 V to 3.399 V) with a minimum output current of 20 mA and 30 mA typical at VIN = 5.5 V. |
| 3 | VIN | power_in | Input (start-up input) terminal; the maximum input voltage is 25 V in the rated range and 28 V absolute maximum. |
