Load Sharing Low Dropout Regulators Using Accurate Current Sensing

Abstract The growing demand for high performance and power hungry portable electronic devices has resulted in alarmingly serious thermal concerns in recent times. The power management system of such devices has thus become increasingly more vital. An integral component of this system is a Low-Dropout Regulator (LDO) which inherently generates a low-noise power supply. Such power supplies are crucial for noise sensitive analog blocks like analog-to-digital converters, phase locked loops, radio-frequency circuits, etc. At higher output power however, a single LDO suffers from increased heat dissipation leading to thermal issues.

This research presents a novel approach to equally and accurately share a large output load current across multiple paralle... (more)
