The LM1086R-5.0V is a low dropout (LDO) positive voltage regulator manufactured by TAEJIN / HTC Korea. This regulator provides a fixed 5.0V output voltage and is designed to deliver up to 1.5A of current. Its key feature is the low dropout voltage, which allows it to maintain a stable output even when the input voltage is only slightly higher than the desired output. This makes it efficient for battery-powered and other applications where input voltage may fluctuate.

Applications

• Post-Regulation for Switching Power Supplies
• Battery Chargers
• Power Management in Portable Devices
• Linear Regulators for Microcontrollers and Microprocessors
