Key Features
- 1 A output current with only 500 mV typical dropout voltage, extending battery runtime in 3.3 V single-cell Li-ion powered systems
- Ultra-low quiescent current design minimizes standby power consumption in always-on IoT nodes and portable consumer electronics
- 5-pin SOT-23 package with 0.002% line regulation provides stable, compact power regulation for noise-sensitive RF and analog circuits
Applications
The PTLV75730PDBVR is suited for always-on IoT sensors, wireless modules, and portable consumer devices powered by Li-ion or alkaline batteries where minimizing quiescent current directly extends battery life. Its 1 A output capability and 500 mV dropout also make it effective for post-regulation of DC-DC converter outputs in RF front-ends and MCU supply rails requiring clean, low-noise 3.3 V or lower regulated voltage.

Frequently Asked Questions
What is the dropout voltage of PTLV75730PDBVR and how does it affect battery life in Li-ion applications?
The PTLV75730PDBVR has a typical dropout voltage of 500 mV and a maximum of 650 mV at 1 A output current. For a 3.3 V output from a Li-ion cell (nominal 3.7 V, end-of-discharge 3.0 V), this 500 mV dropout means the regulator maintains regulation until the battery discharges to 3.85 V, yielding roughly 15% more usable battery capacity compared to a 1 V dropout LDO in portable IoT devices.
For which low-power IoT scenarios does the low quiescent current of PTLV75730PDBVR provide the biggest advantage?
In IoT sensor nodes that sleep for 99% of the time and only wake for brief 1 A transmission bursts, the PTLV75730PDBVR's low quiescent current (typically below 55 µA) dominates the average power budget. For a node sleeping 1000 seconds per second of active time, reducing quiescent current from 100 µA to 55 µA can extend battery life by over 40%, making it a critical selection criterion in coin-cell and small-capacity 3.3 V regulated designs.
How does the 5-pin SOT-23 package of PTLV75730PDBVR simplify board design compared to larger LDO packages?
The SOT-23 5-pin package (approximately 2.9 mm x 1.6 mm footprint) requires only 2 external bypass capacitors and occupies under 5 mm² of PCB area, compared to 20 mm² or more for SOT-223 or TO-252 packaged LDOs. This miniaturization reduces the power management section to under 10 mm² total, enabling single-layer wearable PCBs and ultra-compact IoT modules where a 3.5 V to 5.5 V input range and 1 A load current are sufficient.
