by Qi Deng, Senior Product Marketing Engineer, Analog and Interface Products Division, Microchip Technology Inc., Power Management DesignLine, Mar 29 2006
Focus:
Techniques for improving power supply ripple rejection (PSRR) and output noise performance of linear regulators.
What you’ll learn:
- How to improve the PSRR and output noise perfomance of linear regulators
- How to understand the factors that determine the PSRR and output noise performance of linear regulators
Notes:
A chart at the end of this article compares the PSRR and output noise performance of different types of linear regulators. This article also appears on Microchip Technology's website at www.microchip.com/stellent/groups/designcenter_sg/documents/market_communication/en028091.pdf
