What are the key features of TPS70345PWPG4?
- Dual independent fixed LDO outputs from a single IC simplify power supply design for dual-voltage digital systems
- Ultra-low dropout voltage of 160 mV nominal (250 mV max) maximizes efficiency with input supplies as low as 3.6 V
- 6 V maximum input voltage and Pb-free 24-pin TSSOP package suit battery-powered portable and handheld device designs
What is TPS70345PWPG4 used for?
The TPS70345PWPG4 is well suited for battery-powered portable devices, handheld instruments, and embedded systems requiring two separate regulated voltage rails from a single LDO regulator IC. Its low dropout voltage makes it particularly efficient for applications where the input and output voltages are close together, such as powering DSPs, microcontrollers, and memory from a single Li-Ion or Li-Polymer cell. It is also used in industrial handheld terminals, wireless communication modules, and dual-supply sensor boards where board space and quiescent current are critical design constraints.
