QNH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
QN7070A-1 from QNH, in a SOT-89. 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 | OUT | output | Chip output terminal; the datasheet gives a minimum output sink current IOL of 0.5 mA (1 mA typical) at VDD = 2 V and VOUT = 0.2 V. |
| 2 | VDD | power_in | Chip input (supply) terminal; the operating voltage range is 1.5 V to 12 V, with an absolute maximum VDD of 15 V. |
| 3 | GND | power_in | Chip ground terminal; the output voltage limit is specified relative to GND (Vout from GND-0.3 V to VDD+0.3 V). |
