can be used.

values.

Input Capacitance

CIN

0.5

µF 1. A big enough input

capacitance is needed to

prevent possible impedance

interactions between the

supply and MAS9162.

2. Ceramic, tantalum, and film

capacitors can be used. If a

tantalum capacitor is used, it

should be checked that the

surge current rating is

sufficient for the application.

3. In the case that the

inductance between a battery

and MAS9162 is very small

(< 0.1 µH) 0.47 µF input

capacitor is sufficient.

4. The value of CIN should not be

smaller than the value of CL.

Values given on the table are minimum requirements unless otherwise specified. When selecting capacitors,

tolerance and temperature coefficient must be considered to make sure that the requirement is met in all

potential operating conditions.
