Decoupling Capacitor Recommendations

It is important to provide clean, well regulated power to each power supply. The ON

Semiconductor recommendation for capacitor placement and values are based on our

internal demo camera design and verified in hardware. Note: Because hardware design

is influenced by many factors, such as layout, operating conditions, and component

selection, the customer is ultimately responsible to ensure that clean power is provided

for their own designs.

In order of preference, ON Semiconductor recommends:

1. Mount 0.1F and 1F decoupling capacitors for each power supply as close as possi-

ble to the pad and place a 10 F capacitor nearby off-module.

2. If module limitations allow for only six decoupling capacitors for a three-regulator

design use a 0.1F and 1F capacitor for each of the three regulated supplies. ON

Semiconductor also recommends placing a 10F capacitor for each supply off-mod-

ule, but close to each supply.

3. If module limitations allow for only three decoupling capacitors, use a 1F capacitor

(preferred) or a 0.1F capacitor for each of the three regulated supplies. ON Semicon-

ductor recommends placing a 10F capacitor for each supply off-module but close to

each supply.

4. Give priority to the VAA supply for additional decoupling capacitors.

5. Inductive filtering components are not recommended.

6. Follow best practices when performing physical layout. Refer to technical note TN-

09-131.
