Key Features
- 500 mA output current with only 250 mV typical dropout voltage, maximizing efficiency in battery-powered 3.3 V and 5 V rail designs
- Foldback overcurrent protection automatically reduces output current during short-circuit events, preventing thermal damage
- Ultra-low line regulation of 0.0003% max ensuring stable output voltage across the full 3.5 V to 5.5 V input range
Applications
The PTLV75530PDBVR is designed for powering microcontrollers, FPGAs, and analog front-ends in portable and industrial equipment that draw up to 500 mA from a 3.5 V to 5.5 V supply. Its 250 mV dropout voltage enables efficient regulation even when the input-to-output differential is small, such as in single-cell Li-ion powered designs. The foldback overcurrent protection adds robust fault tolerance for consumer electronics and always-on sensor nodes.

Frequently Asked Questions
What is the dropout voltage of the PTLV75530PDBVR and why does it matter for Li-ion battery applications?
The PTLV75530PDBVR has a typical dropout voltage of 250 mV and a maximum of 325 mV at 500 mA. This low dropout means the regulator continues to regulate correctly until the Li-ion cell discharges to within 250 mV of the output voltage, extending usable battery runtime compared to standard LDOs with 1 V or higher dropout.
How does the foldback overcurrent protection of the PTLV75530PDBVR protect against short circuits?
The PTLV75530PDBVR uses foldback overcurrent protection that automatically reduces both output voltage and current when a short circuit is detected. This limits device power dissipation during fault conditions, preventing thermal runaway and protecting both the LDO and downstream load circuitry without requiring an external protection circuit.
What input voltage range does the PTLV75530PDBVR accept, and does it suit 5 V USB-powered designs?
The PTLV75530PDBVR accepts an input voltage range of 3.5 V to 5.5 V with an absolute maximum of 6 V, making it directly compatible with USB 5 V bus power. It can regulate a stable output from a USB supply while tolerating up to 5.5 V input, with the 6 V absolute maximum providing a safety margin against USB transients.
For a noise-sensitive analog circuit, how good is the line regulation of the PTLV75530PDBVR?
The PTLV75530PDBVR achieves a maximum line regulation of 0.0003%, meaning the output voltage changes by only 0.0003% for a given change in input voltage across the full 3.5 V to 5.5 V input range. This exceptional line regulation makes it well suited for powering precision ADCs, references, and low-noise analog front-ends.
