Regulator_with_output_shutdown_on_dropout_battery_low

Published:2009/7/24 2:28:00 Author:Jessie | From:SeekIC

With this circuit, power is turned completely off when dropout begins (battery low). The circuit will not turn on until (VIN×R2)/( R1+ R2)=2.5 V. This prevents battery creep back from causing oscillation. In some cases, battery voltage will rise temporarily after going low.
