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.

Tradeoffs of LDO Architectures and the Advantages of Advanced Architecture "Capless" LDOs

Power management of battery-powered electronic devices is becoming increasingly more important for the present and future microelectronics industry. This application note details the difference between low dropout (LDO) voltage regulators that use output capacitance and those that do not and how your system designs can benefit from or be improved by not using an output capacitor.

Introduction to Low Dropout (LDO) Linear Voltage Regulators

Linear voltage regulators are key components in any power-management system that requires a stable and ripple-free power supply. A subset of linear voltage regulators is a class of circuits known as low dropout (LDO) regulators. This paper explains the fundamentals of LDOs and introduces Vidatronic’s LDO technology which solves many of the known shortcomings of LDO circuits.
