ADP1714 with Output Voltage Tracking GENERAL DESCRIPTION The ADP1712/ADP1713/ADP1714, available in a tiny, 5-lead TSOT package, are low dropout linear regulators that operate from 2.
5 V to 5.
5 V and provide up to 300 mA of output current.
The low 170 mV dropout voltage at a 300 mA load improves efficiency...
