LM1117T-5.0-OPTECH CO.,LIMITED

Model:LM1117T-5.0

Model:LM1117T-5.0
Manufacturer： Texas Instruments
Stocks：2000
Describe：

5V fixed-output low-dropout linear regulator (LDO), TO-220 package. This device is a classic three-terminal linear regulator that outputs a positive voltage. Under an output current of 800mA to 1A, the typical voltage drop is 1.2V. It integrates internal current limiting protection, thermal shutdown protection, and automatic discharge function to ensure system safety in overload or overheating conditions. The output voltage accuracy is ±2% (the adjustable version of TI/NS can be ±1%, and the fixed version is ±2%). The power supply ripple suppression ratio (PSRR) is up to 75dB at 120Hz. It adopts a TO-220 three-pin surface mount package with a metal heat sink, facilitating the installation of a heat sink to enhance the power dissipation capacity. The operating temperature range varies depending on the brand: 0°C to +125°C (standard version) and -40°C to +125°C (industrial grade version).
