TPS73433DDCR Description

Short technical summary and product information.

The Texas Instruments TPS73433DDCR is a linear voltage regulator designed for applications requiring stable and clean power. It provides a fixed 3.3V output with a maximum current capability of 250mA.

 

Key electrical characteristics include a low quiescent current of 44µA typical, a low dropout voltage of 125mV at 250mA, and excellent power supply rejection ratio (PSRR) of 60dB at 1kHz. The regulator also features ultra-low noise of 28µVrms, making it suitable for noise-sensitive applications. It operates over a wide temperature range of -40°C to 125°C.

 

This device is available in a SOT-23-5 Thin package, suitable for surface mount applications. It includes an enable pin for control and protection features such as over current and over temperature shutdown, as well as undervoltage lockout (UVLO).

 

Applications for the TPS73433DDCR include WiFi, WiMax, printers, cellular phones, smartphones, and handheld organizers.
