GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
GR7533H from GR, 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 | Chip ground terminal (芯片接地端); the datasheet gives no further electrical limit for this pin. |
| 2 | VIN | power_in | Input pin (启动输入端) for the regulator; maximum input voltage is 25 V per the GR7533H selection table, with an absolute maximum of 28 V. |
| 3 | VOUT | power_out | Regulated output (芯片输出端) at 3.3 V ±3% (3.201-3.399 V), sourcing at least 20 mA at VIN = 5.5 V with 1 mA load. |
