The TLV74318PDBVR from Texas Instruments is a low quiescent current, low-dropout linear regulator (LDO) capable of sourcing 300mA. It provides a stable 1.8V output voltage with typical accuracy of 1% and a maximum accuracy of 1.4%.
Key electrical features include an input voltage range of 1.4V to 5.5V, a very low dropout voltage of 125mV at 300mA, and high Power Supply Rejection Ratio (PSRR) of 50dB at 1kHz. The device also includes protection features such as current limit and thermal shutdown.
Designed for applications requiring minimal power consumption, it has a typical quiescent current of 34µA. The TLV74318PDBVR is stable with a small 1µF ceramic output capacitor and features an active pulldown circuit for quick output discharge when disabled. It is supplied in a compact SOT-23-5 package, suitable for surface mounting.
This LDO is particularly useful in battery-operated devices due to its low quiescent current and foldback current control during power-up and enabling. Its active output discharge helps in quickly turning off loads.
