low power, low dropout, rf - linear regulators 9 SGM2030 sg micro corp www.sg-micro.com application note when ldo is used in handheld products, attention must be paid to voltage spikes which could damage SGM2030. in such applications, voltage spikes will be generated at charger interface and v bus pin of usb interface when charger adapters and usb equipments are hot-plugged. besides this, handheld products will be tested on the production line without battery. test engineer will apply power from the connecto r pin which connects with positive pole of the battery. when external power supply is turned on suddenly, the voltage spikes will be generated at the battery connector. the voltage spikes will be very high, and it always exceeds the absolute maximum input voltage (6.0v) of ldo. in order to get robust design, design engineer needs to clear up this voltage spike. zener diode is a cheap and effective solution to eliminate such voltage spike. for example, bzm55b5v6 is a 5.6v small package zener diode which can be used to remove voltage spikes in cell phone designs. the schematic is shown below. ?
