●Notes for use

(1) Absolute maximum ratings

If the absolute maximum ratings for applied voltage and/or operation temperature are exceeded, LSI damage may
result. Therefore, do not apply voltage or use in a temperature that exceeds these absolute maximum ratings. If it is
possible that absolute maximum ratings will be exceeded, use a physical safety device such as a fuse and make sure
that no conditions that might exceed the absolute maximum ratings will be applied to the LSI IC.

(2) GND potential

Regardless of the operation mode, the voltage of the GND pin should be at least the minimum voltage. Actually check
whether or not the voltage at each pin, including transient phenomena, is less than the
GND pin voltage.

(3) Thermal design

The thermal design should be done using an ample margin that takes into consideration the allowable dissipation
under actual use conditions. Perform thermal design in which there are adequate margins by taking into account the
allowable power dissipation in actual states of use.

(4) Shorts between pins and mounting errors

When mounting LSI ICs onto the circuit board, make sure each LSI’s orientation and position is correct. The ICs may
become damaged if they are not mounted correctly when the power is turned on. Similarly, damage may also result if a
short occurs, such as when a foreign object is positioned between pins in an IC, or between a pin and power supply or
GND connection.

(5) Operation in strong electromagnetic field

When used within a strong electromagnetic field, evaluate carefully to avoid the risk of operation faults.

(6) When not using a sag compensation circuit

Connect the sag compensation pin and output pin as closely as possible. There is a danger of high frequency
oscillation. Also make the distance from the output pin (OUT pin, SAG pin) to the 75Ω resistance as short as possible.

(7) When using a sag compensation circuit

Make the length of the output pin (OUT pin, SAG pin) and capacitor as short as possible. There is a danger of high
frequency oscillation. Also make the distance from the output pin (OUT pin, SAG pin) to the 75Ω resistance as short
as possible. If these cautions is not observed in board layout, connect a capacitor (0.01µF～0.1µF) as short as
possible

(8) VGND1(31pin), VGND2(1pin) and AGND(9pin) connection

When to float any one of GND pins(VGND1, VGND2 and AGND) during operation, the internal ESD protection diode
Between VGND1, VGND2 and AGND may be damaged by large current surge. If the abnormal design like floating any
one of GND pins is required, it is advisable to connect external diodes between GND pins. The connection detail of
external diodes is illustrated in Fig.7.
