TPS73734DCQR Description

Short technical summary and product information.

The Texas Instruments TPS73734DCQR is an ultra-low-dropout (LDO) linear voltage regulator designed for efficient power management. It provides a stable 3.4V fixed output voltage and can deliver up to 1A of current. The regulator features an NMOS pass transistor, contributing to low reverse leakage current.

 

Key electrical characteristics include an input voltage range of 2.2V to 5.5V and a typical dropout voltage of 122mV at 1A. It offers excellent load transient response, even with a 1µF output capacitor. The device includes an enable pin for control and protection features such as over current and over temperature shutdown.

 

Packaged in a SOT-223-6 surface-mount package, the TPS73734DCQR is suitable for various electronic applications. Its operating temperature range is -40°C to 125°C. The regulator is designed for stability with 1µF or larger ceramic output capacitors.
