Frequently Asked Questions

What is the output voltage and current capability of the TPS71730DCKT?

The TPS71730DCKT provides a fixed 3V output voltage with ±3% accuracy and can supply up to 150mA of continuous output current, making it suitable for microcontrollers, sensors, and other low-power loads.

What is the dropout voltage of the TPS71730DCKT and why does it matter?

The TPS71730DCKT has a typical dropout voltage of 170mV and a maximum of 300mV. A low dropout voltage means the regulator can maintain a regulated 3V output even when the input voltage is only slightly higher, which is critical for maximizing battery life in portable applications.

What package does the TPS71730DCKT come in and what are its input voltage limits?

The TPS71730DCKT is housed in a 5-Pin SC-70 (SOT-353) package, an extremely compact form factor ideal for space-constrained designs. Its operating input voltage range is 3.3V to 6.5V, with an absolute maximum rating of 7V.

What are typical applications for the TPS71730DCKT?

Typical applications include portable consumer electronics, wearable devices, IoT sensor nodes, handheld instruments, and battery-powered wireless modules that require a stable 3V supply rail with minimal board space.

Are there compatible alternatives or replacements for the TPS71730DCKT?

Compatible alternatives in the TPS717xx family include the TPS71715DCKT (1.5V) and TPS71725DCKT (2.5V) for different fixed output voltages. The TPS71733DCKT provides a 3.3V output in the same SC-70 package if a slightly higher rail is needed.
