What are the key features of TPS70248PWPG4?
- Dual fixed positive LDO outputs from a single 3.6 V to 6 V input supply
- Ultra-low 170 mV typical dropout voltage minimizes power dissipation
- 7 V absolute maximum input rating with robust overvoltage tolerance
- HTSSOP-20 (PDSO20) package enables compact, thermally-efficient PCB layouts
- RoHS-compliant (Pb-free, e4 JESD-609) for green product requirements
What is TPS70248PWPG4 used for?
The TPS70248PWPG4 is well suited for battery-powered portable electronics such as smartphones, tablets, and wearables where dual independent power rails must be maintained from a single Li-ion cell. It is also used in industrial sensor modules and embedded computing boards that need low-noise, tightly-regulated voltage domains with minimal thermal overhead. Its low dropout characteristic makes it a strong fit for always-on subsystems where supply headroom is tight.

Frequently Asked Questions
What is the maximum input voltage the TPS70248PWPG4 can safely handle?
The TPS70248PWPG4 has an absolute maximum input voltage rating of 7 V, while the recommended operating range spans 3.641 V to 6 V. Exceeding 7 V risks permanent device damage, so designers should account for transient spikes in their input filtering circuitry.
How does the 170 mV typical dropout voltage benefit battery-powered designs?
With only 170 mV nominal dropout (275 mV maximum), the TPS70248PWPG4 can maintain regulation closer to battery end-of-discharge, extending usable run time in Li-ion-powered devices operating at 3.3 V output or similar fixed rails.
Which package does TPS70248PWPG4 use and how does it affect thermal management?
The device ships in an HTSSOP-20 (PDSO20) 20-pin small-outline package with an exposed thermal pad, supporting efficient heat dissipation. At typical load currents the 20-pin footprint keeps junction temperatures well within limits, simplifying thermal design for dual-rail applications without external heatsinks.
Can TPS70248PWPG4 replace two single-output LDOs in a dual-rail design to reduce BOM count?
Yes. By integrating 2 independent fixed LDO outputs into one HTSSOP-20 package, TPS70248PWPG4 replaces two discrete single-channel LDOs, cutting component count and reducing board area by approximately 30-40% in compact dual-rail designs.
