What are the key features of TLV1117IDCY?
- 1A output current with low dropout voltage (1.2V typical) for efficient linear regulation
- Wide output voltage range from 1.25V to 13.8V in adjustable configuration
- Built-in thermal shutdown and current limiting for robust protection
- SOT-223 package (DCY) enables excellent thermal dissipation on PCB
- Compatible with standard LDO bypass capacitors for stable operation
What is TLV1117IDCY used for?
TLV1117IDCY is widely used in power supply designs for embedded systems, microcontrollers, and DSPs where a stable regulated voltage is needed from a higher-voltage source. It suits post-regulator applications in battery-powered devices, set-top boxes, and industrial control boards. Its low dropout characteristic makes it ideal for converting 3.3V or 5V rails where headroom is limited.

Frequently Asked Questions
What is the output voltage and current rating of the TLV1117IDCY?
The TLV1117IDCY is an adjustable low-dropout regulator capable of supplying up to 1A of output current. Its output voltage is configurable from 1.25V to 13.8V using two external resistors, making it flexible for a wide range of regulated power supply designs.
What does the 'DCY' suffix mean on the TLV1117IDCY?
The 'DCY' suffix indicates the SOT-223 surface-mount package with a tape-and-reel packaging option. The SOT-223 package features a large exposed pad that significantly improves thermal conductivity, allowing the TLV1117 to dissipate heat effectively on a PCB without a heatsink.
What are the typical applications for TLV1117IDCY?
TLV1117IDCY is commonly used in embedded system power supplies, FPGA and DSP core voltage regulation, battery-powered consumer electronics, industrial control units, and USB-powered devices. Its low dropout voltage (typically 1.2V at 1A) makes it ideal when input-output headroom is constrained.
What protection features does TLV1117IDCY include?
The TLV1117IDCY incorporates internal thermal shutdown protection and output current limiting circuitry. These features prevent damage from excessive junction temperatures or short-circuit conditions, enhancing system reliability in demanding environments.
