Frequently Asked Questions
What is the maximum input voltage the TLV70433DBVT can handle safely?
The TLV70433DBVT accepts an absolute maximum input voltage of 24V, with a normal operating range from 4.3V to 24V. This wide range allows the device to be powered from automotive, industrial, and battery supply rails while maintaining a stable 3.3V output at up to 150mA load current.
How does the ultra-low quiescent current of TLV70433DBVT benefit a battery-powered IoT sensor node?
The ultra-low quiescent current of the TLV70433DBVT, typically in the microamp range, dramatically reduces standby power drain on lithium coin or AA cells. For an IoT node sleeping 99% of the time, this can extend battery life by months compared to a standard LDO with hundreds of microamps of quiescent draw, keeping the 3.3V rail stable across -40°C to 125°C.
Can TLV70433DBVT replace a standard 3.3V LDO in a design powered from a 12V industrial rail?
Yes. With an input voltage range extending to 24V and a fixed 3.3V output, the TLV70433DBVT operates directly from a 12V industrial supply. Its 1.1V maximum dropout voltage at 150mA and the SOT-23-5 footprint make it a compact drop-in solution for replacing older regulators in space-constrained 3.3V industrial control boards.
