What are the key features of TPS70445PWPG4?
- Dual-output fixed LDO with 1.2 V at 1 A and 3.3 V at 2 A from a single 3.6 V to 6 V input, eliminating the need for two separate regulators
- Ultra-low dropout voltage of 160 mV typical and 250 mV maximum at full load, enabling efficient regulation from low-headroom supply rails
- 24-pin HTSSOP package with exposed thermal pad (EP) providing enhanced heat dissipation for sustained dual-rail output currents up to 2 A
What is TPS70445PWPG4 used for?
The TPS70445PWPG4 is well suited for portable battery-powered devices, DSP and FPGA power supply rails, and embedded systems needing simultaneous 1.2 V core and 3.3 V I/O supplies from a single input source between 3.6 V and 6 V. It is also used in wireless communication modules, industrial sensors, and point-of-load converters where compact dual-output LDO regulation with low dropout is required.

Frequently Asked Questions
What output voltages and current ratings does the TPS70445PWPG4 provide?
The TPS70445PWPG4 delivers two fixed output voltages: 1.2 V at up to 1 A and 3.3 V at up to 2 A. Both outputs operate from an input voltage between 3.616 V and 6 V, making it a dual-rail LDO solution for systems requiring simultaneous core and I/O supply voltages.
How does the 250 mV maximum dropout voltage of the TPS70445PWPG4 affect battery-powered designs?
With a dropout voltage of only 160 mV typical and 250 mV maximum at full load, the TPS70445PWPG4 can maintain regulated 3.3 V output from a 3.616 V minimum input, extending battery life in Li-ion powered systems that approach end-of-discharge voltage. This low dropout is critical in portable devices where every millivolt of input headroom affects runtime.
What thermal advantages does the HTSSOP-24 exposed pad package offer for dual-output LDO designs?
The 24-pin HTSSOP package with exposed thermal pad (EP) allows the TPS70445PWPG4 to dissipate heat directly to the PCB ground plane, significantly reducing junction temperature rise at combined output currents of up to 3 A total. This thermal advantage makes it suitable for sustained-load applications where standard SOIC or TSSOP packages without EP would risk exceeding safe junction temperatures.
