TITLV1117-33IDCYR
Overview
The TLV1117-33IDCYR is a low-dropout (LDO) linear voltage regulator designed to provide a fixed 3.3V output at up to 800mA. It is a modern alternative to the industry-standard 1117 series, featuring improved stability and protection features in a compact SOT-223 package. This device is commonly used for local on-card regulation from 5V or higher voltage rails.
Why Choose This Part
The regulator includes internal soft-start to reduce inrush current and foldback current limiting for robust short-circuit protection. It offers a 1 percent output accuracy and operates across a wide industrial temperature range from -40C to 125C. The thermal shutdown and undervoltage lockout features provide an additional layer of reliability in demanding power environments.
Applications
Getting Started
When designing with the TLV1117-33IDCYR, ensure a minimum of 10uF tantalum or low-ESR electrolytic capacitor is placed at the output for stability. Since it is a linear regulator, thermal management is critical; calculate the power dissipation as (Vin - Vout) * Iout and ensure adequate PCB copper area is connected to the SOT-223 tab. This part is a drop-in replacement for most standard 1117 footprint regulators but offers better protection features.
