QN7070A-1

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).
