Frequently Asked Questions
What is the dropout voltage of TC2117-3.3VDBTR and why does it matter for battery-powered 3.3 V designs?
TC2117-3.3VDBTR has a typical dropout voltage of 0.45 V, meaning the input supply only needs to be about 3.75 V to maintain a regulated 3.3 V output. This low dropout makes it effective for use with Li-ion cells or near-depleted alkaline batteries where the supply voltage is close to 3.3 V.
How much output current can TC2117-3.3VDBTR supply, and is it enough for a Wi-Fi or Bluetooth module?
TC2117-3.3VDBTR is rated for up to 800 mA continuous output current, which covers the peak current demand of most Wi-Fi and Bluetooth modules that typically draw 200 mA to 400 mA during transmission bursts while supplying other 3.3 V logic simultaneously.
What is the input voltage range of TC2117-3.3VDBTR, and does it work directly from a USB 5 V rail?
TC2117-3.3VDBTR accepts input voltages from 4.3 V to 6 V, with an absolute maximum of 6.5 V, making it directly compatible with a USB 5 V bus supply. The SOT-223-3 package in tape-and-reel format with an 11-week factory lead time suits medium-volume USB-powered product designs.
