DESCRIPTION
le Ob It integrates one voltage reference, two - operational amplifiers (with ORed outputs ) common collectors), and a current sensing circuit. t(s The voltage reference combined with one c operational amplifier makes it an ideal voltage du controller; the current sensing circuit and the ro other operational amplifier make up the current Obsolete P control loop. SO-8 SOT23-6 The only external components are: – A resistor divider to be connected to the output of the power supply (adaptor, battery charger) to set the voltage regulation by dividing the desired output voltage to match the internal voltage reference value. – A sense resistor having a value and allowable dissipation power which need to be chosen according to the internal voltage threshold. – Optional compensation components (RC).
