SGM2036-ADJ 300mA, Low Power, Low Dropout, CMOS RF Linear Voltage Regulators SOT-23-5 Package operates from a 1.6V to 5.5V input voltage and delivers up to 300mA output current. They are the perfect choice for low-voltage, low-power applications. A low ground current makes this part attractive for battery-operated power systems. The SGM2036-ADJ also offers low dropout voltage to prolong battery life in portable electronics.
When LDO is used in handheld products, attention must be paid to voltage spikes which could damage SGM2036. In such applications, voltage spikes will be generated at the charger interface and VBUS pin of the USB interface when charger adapters and USB equipment are hot-plugged. Besides this, handheld products will be tested on the production line without a battery. The test engineer will apply power from the connector pin which connects with the positive pole of the battery. When the 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 a robust design, the design engineer needs to clear up this voltage spike. Zener diode is a cheap and effective solution to eliminating such voltage spikes.
