Applications
TLV1117CKTTR is widely used in post-regulator stages for microcontroller and FPGA power supplies requiring a stable, adjustable voltage rail up to 0.8 A. Its low 1.2 V dropout voltage makes it well-suited for battery-powered systems where input voltage is close to the desired output. The device also serves industrial and consumer electronics designs needing a simple, low-noise LDO solution across a 2.7 V to 15 V input range.

Frequently Asked Questions
What output current and voltage range does TLV1117CKTTR support?
TLV1117CKTTR supports an adjustable output voltage range from 1.25 V to 13.7 V and delivers up to 0.8 A of continuous output current. This combination makes it suitable for powering microcontrollers, FPGAs, and analog circuits in both fixed and variable supply designs.
How does TLV1117CKTTR perform in battery-operated systems with limited input headroom?
TLV1117CKTTR features a typical dropout voltage of only 1.2 V (maximum 1.3 V), allowing regulation to continue even when the input is only slightly above the output. This low-dropout characteristic is ideal for 3.3 V Li-ion or 5 V USB-powered systems where input voltage may sag under load.
What input voltage range does TLV1117CKTTR accept, and what is the maximum input-output differential?
TLV1117CKTTR accepts input voltages from 2.7 V to 15 V with a maximum input-to-output differential of 13.75 V. This wide input range makes it versatile for use in 5 V, 9 V, and 12 V unregulated supply designs, including wall adapters and industrial control panels.
Is TLV1117CKTTR RoHS-compliant and what package does it use?
Yes, TLV1117CKTTR is Pb-free (RoHS-compliant) and is packaged in a 4-pin DDPAK (surface-mount D-PAK with exposed tab) package. The tab provides an integrated heatsink path, enabling efficient thermal dissipation up to 0.8 A without external heatsink components in many designs.
