Vendor:
Agile Analog
Category:
LDO Voltage Regulator
Low Drop-Out Linear Regulator
The agileLDO is a linear Low Drop-Out voltage regulator (LDO) providing precision and programmable voltage regulation.
Overview
The agileLDO is a linear Low Drop-Out voltage regulator (LDO) providing precision and programmable voltage regulation. The regulator architecture provides a high dynamic performance making it suitable for demanding digital applications. Whilst the low noise and high PSRR lends itself to powering noise-sensitive analog circuits. We have a selection of LDOs, with both capless and externally biased options, supporting a wide range of input voltage, output voltage, and output current.
Agile Analog designs are based on tried and tested architectures to ensure reliability and functionality. Our design methodology is programmatic, systematic and repeatable leading to analog IP that is more verifiable, more robust and more reliable. Our methodology also allows us to quickly re-target our IP to different process options. We support all the major foundries including TSMC, GlobalFoundries, Intel Foundry, Samsung Foundry, UMC and Other Foundries.

The pivotal role power management IP plays in chip design
Power management IP plays a pivotal role in chip design. It is key for achieving the energy efficiency today’s electronic devices demand, but its function extends far beyond this to maintaining high-performance, thermal efficiency, and signal integrity. That’s why chip design engineers are so keen to learn more about power management IP.
The Tradeoffs of Low Dropout (LDO) Voltage Regulator Architectures and the Advantages of "Capless" LDOs
Power management of battery-powered electronic devices is becoming increasingly more important for the microelectronics industry. This white paper details the difference between low dropout (LDO) voltage regulators that use external output capacitors and those that do not, and how your system designs can benefit from not using an output capacitor. Well-designed capless LDO voltage regulators can have multiple benefits, and they are presented here.
Power Management for Internet of Things (IoT) System on a Chip (SoC) Development
There are many factors that must be considered when developing a custom System on a Chip (SoC) for Internet of Things (IoT) applications. Chief among these are the power management circuits on the die. Vidatronic offers this white paper to discuss these considerations and all of the various circuit blocks that can be found in this application. Vidatronic IP solutions are discussed and the benefits they bring to IoT SoC designers.
