What are the key output voltage options?

The output voltage is pin-selectable at startup to 2.5V, 3V, or 3.3V using the VSEL pin.

What is the benefit of the bypass mode?

Bypass mode provides a direct path from the input to the output, reducing quiescent current to 15nA, which is critical for low-power microcontrollers.

What are the primary applications?

It is well-suited for smart meters, remote controls, and home automation systems powered by single 3V Li-MnO2 or dual 1.5V alkaline batteries.

What is the pinout of TPS61291DRVR?

Use the TPS61291DRVR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about TPS61291DRVR pinout to locate pins, power rails, and interface signals before layout.
