TPS73618DCQR Description

Short technical summary and product information.

The Texas Instruments TPS73618DCQR is a high-accuracy, ultra-low-dropout linear voltage regulator designed for portable and battery-powered applications. It features an NMOS pass transistor topology, providing stable operation with or without an output capacitor and offering low reverse leakage current.

 

This regulator provides a fixed 1.8V output voltage with a maximum output current of 400mA. It accepts an input voltage range from 1.7V to 5.5V and boasts an ultra-low dropout voltage of 75mV typical. Key electrical characteristics include low noise performance (30µVRMS typ) and high PSRR (58dB to 37dB).

 

The TPS73618DCQR includes thermal shutdown and current limit protection features. It is supplied in a compact SOT-223-6 surface-mount package, suitable for space-constrained designs. The device is designed for applications requiring clean power, such as post-regulation for switching supplies or noise-sensitive circuitry like VCOs.
