- Integrated supply voltage supervisor (SVS) eliminates external reset IC, reducing BOM cost and board space
- Ultra-low dropout voltage of 83mV typical (140mV max) at full load for efficient battery-powered designs
- Wide input voltage range 3.506V to 6V supports single-cell Li-Ion and multi-cell alkaline battery applications
- JESD-609 e4 Pb-free compliant in 20-pin TSSOP (HTSSOP) package for compact PCB footprint
Applications
The TPS70858PWP is ideal for portable and handheld electronics requiring dual regulated supply rails from a single battery, such as smartphones, tablets, and wearable devices. Its integrated SVS makes it well-suited for microcontroller-based systems needing reliable power-on reset and brownout detection without additional components. It is also used in industrial sensors and communications modules where low quiescent current and tight load regulation are critical.

Frequently Asked Questions
What are the output current ratings of the TPS70858PWP?
The TPS70858PWP provides two independent regulated outputs: one rated at 125 mA and a second rated at 250 mA, allowing it to power two separate voltage rails simultaneously from a single input supply ranging from 3.506V to 6V.
What is the dropout voltage of the TPS70858PWP and why does it matter?
The TPS70858PWP features a typical dropout voltage of 83mV and a maximum of 140mV at full load. This low dropout allows the regulator to maintain regulation even when the input voltage is only slightly above the output voltage, which is critical for extending battery life in portable applications.
What is the integrated SVS feature in the TPS70858PWP?
The TPS70858PWP includes an integrated supply voltage supervisor (SVS) that monitors the input voltage and asserts a reset signal when voltage drops below a threshold. This eliminates the need for a separate supervisory IC, reducing BOM cost and board space in microcontroller and processor-based designs.
What package does the TPS70858PWP come in and what does PWP mean?
The TPS70858PWP is available in a 20-pin HTSSOP (JESD-30 code R-PDSO-G20) package. The PWP suffix in the part number denotes this thermally-enhanced small outline package, which is Pb-free (JESD-609 e4) and suitable for compact, high-density PCB designs.
Can the TPS70858PWP be used in battery-powered designs?
Yes. With an input voltage range starting at 3.506V and dropout as low as 83mV typical, the TPS70858PWP is well-suited for single-cell Li-Ion (3.6–4.2V) and multi-cell alkaline battery applications. Its dual-output architecture and integrated SVS make it a complete power management solution for portable electronics.
