Linear regulators are often used to post-regulate the output of a switching regulator. Benefits include improved stability, accuracy, and transient response performance as well as reduced output impedance. Ideally, along with these performance improvements, the ripples and spikes produced by the switching regulator will be significantly reduced. Virtually all linear regulators encounter some difficulties involving ripple and spikes, especially as frequency increases. This video is excerpted from Linear Technology's Application Note 101, which explains the causes of dynamic limitations of linear regulators and introduces board-level techniques to measure and improve ripple and suppress spikes.
On December 20, 2009, China Telecom issued an announcement stating that "at the request of the Ministry of Industry and Information Technology, starting from December 20, China Telecom's ADSL broadban
Is there a way to achieve this? I am not an electronics major. Can anyone provide relevant information and suggestions? [[i] This post was last edited by q397064399 on 2013-5-18 10:48[/i]]
A: What medium is used to start the development board when the boot media selection pins are all low? The BT_CFG7 of the board we made is low, and BT_CFG6, 5, and 11 are all high, but the core board s
