- Low-dropout regulator - Wikipedia
Low-dropout (LDO) regulators operate similarly to all linear voltage regulators The main difference between LDO and non-LDO regulators is their schematic topology
- Low Drop Out regulator (LDO) | Circuit, Working, Characteristics
A Low Drop out Voltage Regulator or simply an LDO Regulator is an essential part of power management system particularly in battery operated devices LDOs can provide multiple voltage levels with a constant and stable output

- Understanding Low Drop Out (LDO) Regulators
There are two types of linear regulators: standard linear regulators and low dropout linear regulators (LDOs) The difference between the two is in the pass element and the amount of headroom, or dropout voltage, required to maintain a regulated output voltage
- LDO Regulator (Low Dropout Regulator) Basics
・ What Is an LDO? (Definition and Basic Principles) A Low Dropout Regulator (hereafter, LDO) is a voltage regulator circuit that can operate even when the difference between its input and output voltage is tiny
- What Is an LDO Regulator and How Does It Work?
An LDO regulator (low-dropout regulator) is a type of voltage regulator that takes a higher DC voltage and converts it to a stable, lower DC voltage, even when the difference between input and output is very small
- LDO and Linear Regulators Basics: Efficiency, Dropout and Uses
In contrast to standard regulators, LDO regulators mainly use a PNP transistor or a P-channel MOSFET as an output transistor The minimum dropout voltage of such LDO regulators is determined by the collector-emitter voltage (VCE (sat)) or the drain-source voltage (VDS = RDS (ON) × ID)
- Ask The Applications Engineer—37: Low-Dropout Regulators
Low-dropout regulators are distinguished by their ability to maintain regulation with small differences between supply voltage and load voltage For example, as a lithium-ion battery drops from 4 2 V (fully charged) to 2 7 V (almost discharged), an LDO can maintain a constant 2 5 V at the load
