www.DataSheet.co.kr XC6421 Series ■GENERAL DESCRIPTION ETR0353-003 300mA Small High Speed Dual LDO Regulator, Built-in Inrush Current Protection The XC6421 series is an ultra small CMOS dual LDO regulator, mounting 300mA 2-channel small high speed LDO. The series features high accuracy, high ripple rejection and low dropout voltage. The series is capable of high density board installation by the ultra small package of two low on-resistance regulators. Both output accuracies are ±1% by laser trimming. Each regulator can be turned off independently to be in stand-by mode by controlling EN pin. In this state, the electric charge at the output capacitor (CL) is discharged via the internal auto-discharge switch, and as a result the VOUT voltage quickly returns to the VSS level. The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. The high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance. Over current protection circuit and over heat protection circuit are mounted, these circuits start working when output current reaches junction temperature or limit current. The two regulators are completely isolated so that a cross talk during load fluctuations is minimized APPLICATIONS ● Mobile phones ● Portable game consoles ● Portable multimedia player ● Digital still cameras, Camcorders FEATURES Maximum Output Current Operating Voltage Range Output Voltages Output Acc...
