Applications
The TLV1117-18CDCY is widely used in portable electronics and battery-powered devices requiring a stable 1.8V supply for microcontrollers, FPGAs, and memory modules. It is well-suited for post-regulation in distributed power systems and as a point-of-load regulator in industrial and consumer electronics designs. Its low dropout characteristic makes it ideal for systems where input voltage headroom is limited, such as 3.3V-to-1.8V conversion in embedded systems.

Frequently Asked Questions
What is the output voltage and current rating of the TLV1117-18CDCY?
The TLV1117-18CDCY provides a fixed 1.8V output voltage with a maximum output current of 1A. The output voltage accuracy is ±1% over the full operating temperature range, making it suitable for precision power supply applications.
What is the dropout voltage of the TLV1117-18CDCY?
The TLV1117-18CDCY has a typical dropout voltage of 1.1V at 1A load current. This means a minimum input voltage of approximately 2.9V is required to maintain the regulated 1.8V output, which is beneficial for systems with limited voltage headroom.
What package does the TLV1117-18CDCY come in and what are its thermal characteristics?
The TLV1117-18CDCY is available in a SOT-223 surface-mount package, which offers good thermal dissipation. The device includes built-in thermal shutdown protection that activates when junction temperature exceeds safe limits, preventing damage during overload conditions.
What are the typical applications for the TLV1117-18CDCY?
The TLV1117-18CDCY is commonly used to power microcontrollers, FPGAs, DDR memory, and other 1.8V logic circuits. It is ideal for 3.3V-to-1.8V point-of-load regulation in embedded systems, IoT devices, consumer electronics, and industrial control boards.
