Frequently Asked Questions
What is the dropout voltage of the TPS76850QDRG4 and why does it matter for battery-powered designs?
The TPS76850QDRG4 has a typical dropout voltage of 0.23 V and a maximum of 0.38 V at rated load. This low dropout allows the regulator to continue delivering a regulated 5.0 V output even when the input supply has sagged to as low as 5.38 V, extending usable battery life compared to older regulators requiring 1 V or more of headroom.
What input voltage range can the TPS76850QDRG4 tolerate, including transient conditions?
The TPS76850QDRG4 accepts a continuous input voltage from 2.7 V minimum to 10 V maximum, with an absolute maximum rating of 13.5 V for transients. This allows it to be powered from a nominal 9 V wall adapter or a regulated 6 V rail while withstanding occasional voltage spikes common in automotive and industrial power environments.
How does the 0.00365% line regulation specification of the TPS76850QDRG4 compare for analog circuit powering?
With a maximum line regulation of 0.00365% (approximately 1.8 mV output change per volt of input change at 5 V output), the TPS76850QDRG4 provides a stable reference-quality supply suitable for powering precision ADCs, op-amps, and DACs where power supply noise above 5 mV would corrupt measurement accuracy in 12-bit or 14-bit signal chains.
