TITLV1117-50IDCYR
Overview
The TLV1117-50IDCYR is a low-dropout (LDO) linear voltage regulator designed to provide a fixed 5V output at up to 800mA. It is capable of operating over a wide industrial temperature range of -40C to 125C, making it suitable for demanding thermal environments. This device includes internal protection features such as foldback current limiting and thermal shutdown to ensure robust operation.
Why Choose This Part
This regulator offers high ripple rejection of 75dB at 120Hz, which is excellent for minimizing power supply noise in sensitive applications. Its SOT-223 package provides a good balance between small surface-mount footprint and thermal dissipation capabilities. Built-in soft-start and current foldback mechanisms protect both the regulator and the load during power-up or fault conditions.
Applications
Key Specifications
Getting Started
When designing with the TLV1117-50, ensure a minimum load current of 1.7mA is maintained for stability, as specified for typical operation. Place a 10uF tantalum or low-ESR electrolytic capacitor close to the output pin to ensure stable regulation and improve transient response. Consult the datasheet for PCB copper pour requirements to manage the thermal dissipation of the SOT-223 package under high load current or high dropout voltage conditions.
