Overview
Targeted in SMIC 0.13μm 1.2v/3.3v logic process, current design of Power Regulator is to provide 1.8v power supply which is regulated from the single 3.3v supply. This IP can work in the LDO mode, which means the 3.3v supply input can drop to 1.65v at minimum, accordingly in the LDO mode, output voltage will drop by Vdrop from the input supply voltage. The minimum output current driver capability is 300mA. This IP cannot be used alone. It must be used together with another VeriSilicon IP, S13V33_PRG_05 because the reference voltage and current bias should come from S13V33_PRG_05. This particular physical IP has the scaled up version of S13V33_PRG_04B which is designed to be used in foundry’s 0.11um (90% shrink) process.

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.
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.
Power management poses challenges
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.
The vast array of on-chip LDO options and characteristics can make the selection process complex.
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.
