TPS70345PWPR Description

Short technical summary and product information.

The Texas Instruments TPS70345PWPR is a dual-output, low-dropout (LDO) linear voltage regulator designed for split-supply applications. It offers independent enable functions, power-on reset with a 120ms delay, and power good output for Regulator 1.

 

This device features fixed output voltages of 3.3V for one regulator and 1.2V for the other, with each capable of supplying up to 1A of current. The input voltage range is from 2.7V to 6V. Key electrical characteristics include a low dropout voltage of 160mV typical at 1A, and a low quiescent current of 185µA typical. It also provides features like over current, over temperature, reverse polarity, and undervoltage lockout protection.

 

The TPS70345PWPR is housed in a 24-pin HTSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C, making it suitable for various industrial and consumer electronics applications requiring stable dual voltage rails.
