This article presents a fast-transient radiation-hardened low-dropout (LDO) voltage regulator integrated in standard 0.6-μm BiCMOS technology for space and other harsh radiation environment applications. The fabricated LDO consumes 150- μA quiescent current at 6-A maximum output current. An of 300 mV which corresponds to an ultralow R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xl...

A novel design for a low dropout (LDO) voltage regulator is presented and dedicated to power many sections of a typical cellular handset. However, these baseband, RF, and audio sections have different requirements that influence which LDO is most appropriate. After discussion of the specific requirements, different LDOs are recommended. Also, some LDO design techniques are briefly discussed to ...

The goal of internal frequency compensation of a low dropout voltage regulator (LDO) is the selection of a small-value, ESR-independent output capacitor. Cascode compensation formed by a common-gate transistor acting as a current buffer, an optional series resistor, and a compensation capacitor creates a dominant pole and a left-halfplane (LHP) zero, allowing adequate phase margin and stable LD...

© 2010 ETRI Journal, Volume 32, Number 4, August 2010 In this paper, we present a low-voltage low-dropout voltage regulator (LDO) for a system-on-chip (SoC) application which, exploiting the multiplication of the Miller effect through the use of a current amplifier, is frequency compensated up to 1-nF capacitive load. The topology and the strategy adopted to design the LDO and the related compe...

Low-dropout (LDO) voltage regulator has fascinated industry professionals and academia for the past few decades, this trend is expected to continue in coming years. The high demand a stable linear architecture that performs well systems-on-chip (SoC) power management integrated circuits (PMICs) key factor driving innovation with different complementary metal-oxide-semiconductor (CMOS) technolog...

Abstract. A new multi-loop controlled low dropout (LDO) regulator featuring with improved transient response and low quiescent current is presented in this paper. The proposed Multi-Loop Control (MLC) technique adopting both feed-back and feed-forward control methods to realizes the fast response ability by regulating the load current and output voltage through separate loops rapidly. In additi...
