Notes : For the actual usage, please follow the power supply voltage, load and ambient temperature conditions to ensure that there is
enough margin and the thermal design does not exceed the allowable value.

CAUTION
Although this IC has built-in ESD protection circuit, it may still sustain permanent damage if not handled
properly. Therefore, proper ESD precautions are recommended to avoid electrostatic damage to the MOS
gates.

Notes : Voltage values, unless otherwise specified, are with respect to GND.
GND is voltage for AGND, PGND. AGND = PGND
VIN is voltage for AVIN, PVIN. VIN = AVIN = PVIN.
Do not apply external currents or voltages to any pin not specifically mentioned.
*1 : (VREG + 0.3) V must not exceed 6 V.
*2 : (VIN + 0.3) V must not exceed 30 V.
