TPS73233DCQR Description

Short technical summary and product information.

The Texas Instruments TPS73233DCQR is a low-dropout (LDO) linear voltage regulator designed for portable and battery-powered equipment. It features a fixed 3.3V output voltage and can supply up to 250mA of current. This NMOS-based regulator is stable with or without an output capacitor, offering excellent load transient response.

 

Key electrical characteristics include an ultra-low dropout voltage of 40mV typical at 250mA, low noise of 30µVRMS (10kHz to 100kHz), and high PSRR. The device operates over an input voltage range of 1.7V to 5.5V and includes protection features such as thermal shutdown, overcurrent, and short-circuit protection.

 

The TPS73233DCQR is available in a SOT-223-6 package, suitable for surface mounting. Its low quiescent current, less than 1µA in shutdown mode, makes it ideal for power-sensitive applications. The regulator is also designed with reverse current protection.

 

Applications include post-regulation for switching supplies, noise-sensitive circuitry like VCOs, and point-of-load regulation for DSPs, FPGAs, and microprocessors.
