Applications
The TC1017-3.3VCTTR is widely used in portable consumer electronics, IoT sensor nodes, and wireless modules that require a stable 3.3 V rail from a single-cell lithium or alkaline battery pack. Its low dropout voltage of 0.285 V nominal allows the regulator to maintain regulation even when the input supply is close to the output voltage, extending battery run time. The active-low shutdown pin makes it easy to implement system-level power sequencing and sleep-mode power gating in microcontroller-based designs.

Frequently Asked Questions
What is the output voltage and maximum load current of the TC1017-3.3VCTTR?
The TC1017-3.3VCTTR provides a fixed 3.3 V output and can supply up to 150 mA of load current. With a nominal dropout voltage of only 0.285 V, it maintains regulation even when the input is as low as approximately 3.6 V under light load conditions, making it suitable for battery-powered circuits.
What input voltage range does the TC1017-3.3VCTTR support, and what is the absolute maximum input?
The TC1017-3.3VCTTR operates from an input voltage range of 4.3 V to 6 V for specified performance. The absolute maximum input voltage is 6.5 V. Exceeding this level risks permanent damage to the device, so input transient protection should be considered in systems with noisy or unregulated supplies.
How does the shutdown pin on the TC1017-3.3VCTTR help reduce power consumption in battery designs?
The active-low shutdown pin allows a microcontroller or power management IC to disable the TC1017-3.3VCTTR output entirely, reducing quiescent current to microamp levels. This is critical in IoT and wearable devices operating from coin cells or AA batteries, where even milliamps of standby current can significantly reduce battery life over weeks or months of deployment.
Why is the SOT-23-5 package a good fit for compact PCB designs using the TC1017-3.3VCTTR?
The SOT-23-5 package measures approximately 2.9 mm x 1.6 mm, consuming very little PCB real estate. This compact footprint is ideal for wearables, hearing aids, and miniature sensor modules where board area is at a premium. Only a few bypass capacitors are needed externally, keeping the total solution size minimal.
