What are the key features of TPS7A1011PDSER?
- Ultra-low quiescent current LDO with 0.75 V minimum VIN enabling regulation from near-dead battery cells and energy harvesting sources
- 90 mV maximum dropout voltage at 300 mA output ensuring regulation is maintained even with heavily discharged 1.5 V alkaline or 1.8 V LiFePO4 batteries
- Enable pin with -40°C to +125°C operating range in a compact 6-pin WSON package for always-on IoT and wearable power management
What is TPS7A1011PDSER used for?
The TPS7A1011PDSER is optimized for battery-powered IoT sensors and wearable devices that must maximize run time on coin cells, alkaline batteries, or energy harvesters, where its ultra-low IQ keeps standby current in the sub-microamp range. The 0.75 V minimum input allows it to continue supplying regulated output voltage as batteries discharge well below their nominal voltage, extending operational life beyond competing LDOs with higher input requirements. It also serves in always-on sub-circuits within smartwatches, wireless sensor nodes, and medical patches that draw continuous low-level power from a primary cell over multi-year lifetimes.

Frequently Asked Questions
How does the TPS7A1011PDSER's ultra-low quiescent current extend battery life in a coin-cell IoT sensor compared to a standard LDO?
A typical CR2032 coin cell stores approximately 225 mAh of charge. If a standard LDO draws 50 µA quiescent current versus the TPS7A1011PDSER's sub-1 µA IQ in standby, the idle current difference alone equates to over 25 years of additional runtime. For an IoT sensor that spends 99% of its time in sleep mode drawing only 2 µA total, the TPS7A1011PDSER's ultra-low IQ ensures the LDO itself consumes less than 50% of that standby budget, enabling 5 to 10 year battery life on a single CR2032.
What is the minimum input voltage the TPS7A1011PDSER can accept and why does that matter for alkaline battery applications?
The TPS7A1011PDSER accepts input voltages as low as 0.75 V absolute minimum, though normal operation starts at 1.6 V. An alkaline AA cell discharges from 1.5 V nominal down to approximately 0.9–1.0 V before being considered depleted, and with a 90 mV maximum dropout voltage, the LDO can continue regulating a fixed output voltage like 0.8 V even from a nearly exhausted 1.0 V cell. This deep discharge capability extracts maximum energy from low-cost primary batteries compared to LDOs requiring 1.8 V or higher minimum input.
In a design comparing the TPS7A1011PDSER to a larger SOIC LDO, what PCB area saving does the 6-pin WSON package provide?
The 6-pin WSON package occupies approximately 4 mm² (2x2 mm footprint), compared to roughly 29 mm² for a standard 8-pin SOIC LDO. This represents more than 85% reduction in component footprint, freeing over 25 mm² per rail in densely populated wearable and IoT PCBs. Combined with the minimal external passives required — typically a 1 µF input capacitor and 1 µF output capacitor — the complete solution area remains under 15 mm², enabling highly integrated multi-rail power trees in sub-1 cm² board sections.
