Notes:
4. AL8805 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 34 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 . As SOT25 doesn’t have an exposed tab or exposed pad the majority of heat flow is though pin 2 down to ground.
