... GENERAL DESCRIPTION The SG2003/A and SG2004/A low-power, low-noise, low-dropout, CMOS linear voltage regulators operate from a 2.5V to 5.5V input and deliver up to 400mA (400mA peak SG2003 only). They are the perfect choice for low voltage, www.DataSheet4U.com low power applications. An ultra low ground current (120 at 400mA output) make them attractive for battery µ ...

... Application Notes When LDO is used in handheld products, Attention must be paid to voltage spike which would damage SG2003 and SG2004. In such applications, voltage spike will be generated at changer interface and V pin of USB interface when changer adapters and USB equipments are hot-inserted. Besides this, handheld products will be tested on the production line on the condition of no battery ...
