Frequently Asked Questions
What is the maximum dropout voltage of TPS7133QPE4 and why does it matter for battery applications?
The TPS7133QPE4 has a maximum dropout voltage of 400mV, meaning it can regulate output even when the input is only 400mV above the output. This low dropout extends usable battery life in 3.3V or 5V systems by allowing operation closer to full battery discharge.
How precise is the TPS7133QPE4 output regulation under line and load variations?
The device specifies 0.027% maximum line regulation and 0.12% maximum load regulation, delivering highly stable output voltage across changing input supply voltages and varying load currents, making it suitable for precision analog front-end circuits and sensor references.
Which package does TPS7133QPE4 use and how does it aid prototyping?
The TPS7133QPE4 is housed in an 8-pin DIP (PDIP) through-hole package with 2.54mm lead pitch, which fits standard breadboards and DIP sockets, greatly simplifying early-stage prototyping and laboratory evaluation before committing to a surface-mount design.
When would an engineer choose TPS7133QPE4 over a standard NPN-based LDO regulator?
A PMOS LDO like the TPS7133QPE4 draws negligible gate current from the output, unlike NPN-based LDOs that require base current sourced from the output. This makes TPS7133QPE4 superior in low-quiescent-current, battery-powered systems where supply efficiency with dropout as low as 400mV is critical.
