Recent Advances on Linear Low-Dropout Regulators

IEEE Transactions on Circuits and Systems II: Express Briefs, 2021
This brief revises the recent design trends of linear low-dropout regulators. The design issues and advantages of analog LDOs (ALDO) are discussed. High-performance operation and high rejection to supply noise when delivering large current values is a major advantage of the ALDO, but transient response when transitioning from standby operation to full ...

Design of a Low-Dropout Linear Regulator

2020 IEEE International Conference on Artificial Intelligence and Information Systems (ICAIIS), 2020
This paper introduces a low-dropout linear regulator with an operating voltage of 2.5V. An anti-overshoot circuit is added to the error amplifier, and the regulator module is optimized based on circuit stability performance; Add trim function to feedback resistance network so that LDO can output different voltage values such as 1.1V, 1.8V and 2.2V ...

An Output-Capacitorless Ultra-Low Power Low-Dropout Regulator

Journal of Circuits, Systems and Computers, 2017
This paper proposes an output-capacitorless low-dropout (LDO) regulator with ultra-low quiescent power. It applies an adaptive error amplifier to improve the bandwidth and transient response during heavy load, and a second gain stage to improve the stability during light load.

A sub-threshold ultra-low power low-dropout regulator

2017 International SoC Design Conference (ISOCC), 2017
In this paper, a wide range low dropout (LDO) with low current consumption is presented. The circuitry is constructed by a sub-threshold voltage error amplifier (EA). The transistors of EA operate in the sub-threshold region, which allows a remarkable reduction in the minimum supply voltage and current consumption. In the condition of input voltage 2 ∼

Low overshoot, low dropout voltage regulator with level detector

2010 IEEE Dallas Circuits and Systems Workshop, 2010
An ultra-small, low power, low dropout (LDO) voltage regulator is presented which tracks the output voltage with threshold voltages of the underlying process technology. The topology of the regulator is extremely simple because it does not use an error amplifier.

Low dropout voltage regulator for wireless applications

2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289), 2003
Low dropout voltage regulators (LDO) are widely used in portable communication products such as cellular phones, pagers, and laptops. In this paper, we present a wide range load (100 mA) LDO designed with 0.25 /spl mu/m CMOS process. By using a fast transient loop, we obtained high performance in transient response and output stability.

A novel dual-feed low-dropout regulator

Journal of Semiconductors, 2015
A novel dual-feed (DF) low-dropout (LDO) is presented. The DF-LDO adopts dual control loops to maintain the output voltage. The dual control loops include a feedback loop and a feedforward loop. There is an equilibrium point in dual control loops, and the equilibrium point is the output voltage of the DF-LDO.

Design of an adjustable,low voltage, low dropout regulator

Proceedings of the Fifth IEEE International Caracas Conference on Devices, Circuits and Systems, 2004., 2005
This paper presents the design of a low voltage, low dropout (LDO) regulator with two different output voltages (1V or 1.8V). The basic function of an LDO is to optimize the battery life of portable devices and to provide a constant output voltage to drive small sub-circuits. The proposed LDO was designed using 0.35/spl mu/m CMOS technology. The design

Ferroelectric Domain Wall Delayer and Low-Dropout Regulator

ACS Applied Materials & Interfaces
A switching-type power converter providing an accurate and stable switching output voltage against line/load variations and power supply ripple is mostly complicated in system-on-chip power management integrated circuits (PMICs) within a limited occupation area. Here we fabricated domain wall (DW) nanodevices using an X-cut LiNbO3 thin film on silicon.
