TLV73318PDBVR Description

Short technical summary and product information.

The TLV73318PDBVR from Texas Instruments is a low-dropout linear regulator (LDO) designed for efficient power management. It provides a stable 1.8V output voltage with a maximum output current of 300mA.

Key electrical specifications include a wide input voltage range of 1.4V to 5.5V, a very low dropout voltage of 0.3V at 300mA, and a typical quiescent current of 34µA. The regulator also features high Power Supply Rejection Ratio (PSRR) and protection against overcurrent, over-temperature, short circuits, and undervoltage lockout (UVLO).

This LDO is designed with a modern capacitor-free architecture, ensuring stability without the need for input or output capacitors. This feature significantly reduces the overall solution size and can eliminate inrush current at startup. The device is available in a compact SOT-23-5 package, suitable for surface mount applications.

The TLV73318PDBVR is ideal for various applications requiring a compact and efficient voltage regulation solution, such as portable electronics, battery-powered devices, and power management subsystems.
