Low dropout voltage regulators (LDOs) are common in many applications. State of the art Power-Management Integrated Circuits (PMICs) for smartphones and other portable devices include over a dozen LDOs. LDOs are also found integrated onto Microprocessors, Graphics Processing Units (GPUs), and in many other Systems on a Chip (SOCs).
LDOs come in many different shapes and sizes and there is no standard one-size-fits-all option. To know which LDO you need, you must first define the application of your LDO and then determine several required specifications. To help you get started, we’ve compiled a list of 5 basic questions you should know the answer to when you begin your search for the right LDO.[Read more…] about 5 Basic Questions You Should Answer Before Selecting an LDO
