of External Parts C1 (C1) Feedback capacitors Related to low roll-off frequency fL for

3dB (100µF, fL=60Hz).

A capacitance value of 47µF to 100µF is recommended.

Increasing the capacitance value makes the starting time (ts) later.

Low idling current (20mA/2 channels) enabling prolonged battery life.
Less dependence of idling current on VCC.
High power (5.3W typ. ×2).
High ripple rejection (60dB at steady state). Since filters are arranged in 3 stages (including 1 stage inside the IC) to attain satisfactory ripple rejection at transient state, ripple occuring at the time of motor start can be prevented from mixing in.
Low pop noise at the time of power supply ON/OFF and goo.
