Frequently Asked Questions
What is the dropout voltage of the TPS75901KC and why does it matter for battery-powered designs?
The TPS75901KC has a typical dropout voltage of 0.4 V, which means it can regulate output even when the input supply is only 0.4 V above the desired output. This low dropout extends battery life in portable applications because the device continues to regulate until the battery discharges close to the target output voltage, reducing wasted energy compared to standard LDOs with 1 V or higher dropout.
Over what input voltage range can the TPS75901KC operate reliably?
The TPS75901KC operates across an input voltage range of 2.8 V to 5.5 V, making it compatible with single-cell Li-Ion batteries, regulated 3.3 V and 5 V rails, and other common supply voltages used in embedded and consumer electronics designs.
How does the TPS75901KC compare to a fixed-output LDO when designing an adjustable power rail?
Unlike fixed-output LDOs that require selecting a specific output voltage variant, the TPS75901KC offers an adjustable output set by external resistors, giving designers flexibility to target any voltage within the 0.4 V to 5.1 V output range. Line regulation is max 0.1 %/V and load regulation is max 0.35%, ensuring tight accuracy for sensitive analog and digital loads without sourcing multiple fixed-voltage parts.
