TITLV1117-18IDCYR
Overview
The TLV1117-18IDCYR is a fixed-output low-dropout (LDO) linear regulator designed to provide a stable 1.8V rail from input sources up to 15V. It is capable of delivering up to 800mA of output current, making it suitable for powering digital logic, microcontrollers, and interface circuits. The device includes internal protection features such as over-current and over-temperature shutdown to ensure system reliability.
Why Choose This Part
This regulator offers a high Power Supply Rejection Ratio (PSRR) of 75dB at 120Hz, which helps filter ripple from primary power stages. Its SOT-223 package provides a good balance between thermal performance and board space, while the wide operating temperature range of -40 to 125 degrees Celsius supports industrial-grade environments.
Applications
Key Specifications
Getting Started
To implement this LDO, place a minimum 10uF tantalum capacitor at the output for stability and a 0.1uF ceramic capacitor at the input to filter high-frequency noise. Ensure the PCB copper pour around the SOT-223 tab is sufficient to dissipate heat, especially when the input-to-output voltage differential is high at full 800mA loads.
