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.

As discussed in Part 1 of our ADC Topology Series, Analog-to-Digital converters (ADCs) are used as an interface element between the analog and digital worlds to convert an analog input into a corresponding digital output.

There is a continuing trend in the industry toward achieving higher data throughput in both wired and wireless digital communication systems. This trend results in increasingly more demanding requirements from ADCs in terms of sampling rate and conversion accuracy. Meeting these specifications requires the use of different ADC topologies. One such topology is the Dual-Slope ADC.

As discussed in Part 1 of our ADC Topology Series, Analog-to-Digital converters (ADCs) are used as an interface element between the analog and digital worlds to convert an analog input into a corresponding digital output.

Some examples of situations where ADCs are necessary include:

• When data from the analog domain, through sensors or transducers, should be digitally processed.
• When transmitting data between chips through long range wireless radio links in high speed wireline transceivers between chips either on the same printed circuit board (PCB) or in a multi-die module.
• When used in analog test equipment (ATE) testing.

There is a continuing trend in the industry toward achieving higher data throughput in both wired and wireless digital communication systems. This trend results in increasingly more demanding requirements from ADCs in terms of sampling rate and conversion accuracy. Meeting these specifications requires the use of different ADC topologies. One such topology is the Flash ADC.
