DDC112: Need suggestion for power supply

Part Number: DDC112
Other Parts Discussed in Thread: LM76005

Hello

I want to select a Low Noise Linear regulator to supply 5V power to DDC112 for maximum measurement accuracy.

Input to the Linear regulator will be 12V from DC-DC Buck converter LM76005. Maximum current requirement is less than 300mA.

Can you suggest any suitable wide input range low noise Linear/LDO regulator which can provide accurate 5V power to DDC112 ?

Or any other solution to provide power to DDC112 for maximum measurement accuracy ?

Hi Bhanu,

Thanks for the post.

TI has many low-noise LDO that is suitable for the DDC112 application. One recommendation will be the TPS74A47, a low-noise, high-PSRR, low-dropout voltage regulator. Please see the TPS74A47 product link below for your reference. To get the best performance, please refer to the layout recommendation for the device in the datasheet.
