Notes:
4. AL8807 does not have a low power standby mode but current consumption is reduced when output switch is inhibited: V SENSE = 0V. Parameter is
tested with V CTRL ≤ 2.5V
5. Refer to figure 35 for the device derating curve.
6. Test condition for SOT25: Device mounted on FR-4 PCB (25mm x 25mm 1oz copper, minimum recommended pad layout on top layer and thermal
vias to bottom layer ground plane. For better thermal performance, larger copper pad for heat-sink is needed.
7. Test condition for MSOP-8EP: Device mounted on FR-4 PCB (51mm x 51mm 2oz copper, minimum recommended pad layout on top layer and
thermal vias to bottom layer with maximum area ground plane. For better thermal performance, larger copper pad for heat-sink is needed
8. Dominant conduction path via Gnd pin (pin 2).
9. Dominant conduction path via exposed pad.
