Frequently Asked Questions
What is the dropout voltage of the TPS70158PWPR under maximum load, and why does it matter for 5 V input designs?
The TPS70158PWPR has a maximum dropout voltage of 275 mV and a nominal dropout of 170 mV, meaning it can regulate outputs up to 5.725 V from a 6 V input. In a 5 V supply system, this low dropout allows the regulator to maintain stable dual outputs with minimal input voltage overhead, improving efficiency in battery-operated products.
How does the dual-output architecture of the TPS70158PWPR reduce BOM cost compared to using two separate single-output LDOs?
By integrating two independent LDO regulators into a single 20-pin SOIC package, the TPS70158PWPR eliminates the need for two separate ICs, reducing board space and simplifying the power management BOM. A 4.3 V to 6 V single supply powers both rails, also reducing bulk capacitor requirements on the input side.
Over what input voltage range can the TPS70158PWPR operate, and what protection does it provide at the upper limit?
The TPS70158PWPR operates with an input voltage from 4.3 V to 6 V under normal conditions, with an absolute maximum rating of 7 V. Exceeding 7 V risks permanent device damage, so designers should include input transient clamping in automotive or industrial environments where voltage spikes above 6 V are possible.
For a wireless sensor node powered by 4x AA batteries at 6 V, how well does the TPS70158PWPR handle the supply as batteries discharge?
The TPS70158PWPR's 4.3 V minimum input voltage matches well with a 4x AA battery pack that discharges from 6 V toward 4.8 V. With a 275 mV maximum dropout, both regulated outputs remain stable as long as the battery voltage stays above the output voltage plus 275 mV, giving extended usable runtime before regulation drops out.
