Frequently Asked Questions
What is the dropout voltage of the TPS71711DCKT?
The TPS71711DCKT has a typical dropout voltage of 170mV and a maximum of 300mV at 150mA output current. This low dropout enables operation from low battery voltages while maintaining regulation, extending battery life in portable applications.
What is the input voltage range for the TPS71711DCKT?
The TPS71711DCKT operates with an input voltage range of 2.5V to 6.5V (absolute maximum 7V), making it compatible with single-cell Li-ion batteries, 3.3V, and 5V supply rails commonly found in microcontroller-based and wireless communication systems.
Why is the PSRR important for the TPS71711DCKT?
The TPS71711DCKT is specifically designed with high power supply rejection ratio (PSRR), which attenuates noise and ripple from the input supply. This is critical for powering RF transceivers, audio circuits, ADC references, and other analog components where power rail noise directly degrades system performance.
Is the TPS71711DCKT RoHS compliant?
Yes, the TPS71711DCKT is fully RoHS compliant and lead-free, indicated by Texas Instruments' Pb-free code. It meets all major environmental standards for use in consumer, industrial, and telecommunications applications worldwide.
What package does the TPS71711DCKT use and what are its dimensions?
The TPS71711DCKT is housed in a 5-pin SOT-23 (DCK) package, one of the most common small surface-mount packages in the industry. This package is extremely compact, enabling dense PCB layouts in space-constrained wearable, portable, and IoT device designs with standard reflow assembly compatibility.
