LM3687TL-1812/NOPB Product Details
LM3687TL-1812/NOPB Description
The LM3687TL-1812/NOPB is a step-down DC-DC converter with an integrated low dropout Linear Regulator optimized for powering ultra-low voltage circuits from a single Li-lon cell or 3-cell NiMH/NiCd batteries. It provides a dual output with fixed output voltages and combined load current up to 750mA in post-regulation mode or 1100mA in the independent mode of operation, over an input voltage range from 2.7V to 5.5V. There are several different fixed output voltage combinations available.
