The Texas Instruments TPS73218QDCQRQ1 is a high-accuracy, low-dropout linear voltage regulator designed for automotive applications. It features a fixed 1.8V output voltage and can supply up to 250mA of current.
This LDO regulator utilizes an NMOS pass element topology, providing stable operation with or without an output capacitor and offering high reverse current blocking. Key electrical characteristics include an ultra-low dropout voltage of 40mV typical at 250mA, low noise of 30 μVRMS (10 kHz to 100 kHz), and an overall accuracy of 1% over line, load, and temperature variations. The device operates from an input voltage range of 1.7V to 5.5V.
Designed for noise-sensitive circuitry such as VCOs and post-regulation for switching supplies, the TPS73218QDCQRQ1 includes features like Enable control, thermal shutdown, and foldback current limiting for protection. It is AEC-Q100 qualified, rated for Temperature Grade 1 (-40°C to 125°C ambient operating temperature).
The TPS73218QDCQRQ1 is available in a SOT-223-6 surface-mount package, suitable for various automotive and industrial applications requiring reliable power management.
