The LM1086IS-5.0/NOPB with Linear Voltage Regulator IC Positive Fixed 1 Output 1.5A DDPAK/TO-263-3 is a voltage regulator manufactured by Texas Instruments. It is a single, low-dropout, positive voltage regulator with an output of 1.5A and an input voltage range of 1.2 V to 20 V. It features a input-output voltage drop as low as 1.3V, an adjustable output voltage range of 1.2 V to 20 V, and over-temperature and over-current protection. It also features an on/off control interface for system control and power saving and is designed for DPAK/TO-263-3 packages and is rated up to +125C ambient. This voltage regulator is ideal for powering microprocessors, application-specific ICs, digital signal processors, communication systems, and other low-voltage circuits.
