The TLV74018PDBVR from Texas Instruments is a low-quiescent-current, low-dropout linear regulator (LDO) featuring a fixed 1.8V output and up to 300mA output current. It supports an input voltage range from 1.4V to 5.5V and provides a typical accuracy of 1%, making it suitable for power-sensitive portable and embedded applications.
The TLV74018PDBVR incorporates foldback overcurrent protection and inrush current control to limit excessive current during startup and enable operation. It features a typical quiescent current of 50µA, a typical dropout voltage of approximately 460mV at 300mA, and a power supply rejection ratio of approximately 65dB at 1kHz.
An active output discharge circuit helps quickly discharge the output load when the regulator is disabled. The TLV74018PDBVR is supplied in a compact 5-pin SOT-23 (DBV) surface-mount package and operates over a temperature range of -40°C to +85°C. Typical applications include portable media players, notebooks, streaming devices, printers, set-top boxes and other low-power electronic systems.
