1 / 23 page 1/23 XC6415 Series Dual LDO Regulators with ON/OFF Switch ■ GENERAL DESCRIPTION XC6415 series are highly accurate, Dual, low noise, CMOS LDO voltage regulators. Performance features of the series include low output noise, high ripple rejection rate, and low dropout. Extremely dense power supply circuit can be organized with a 2 channeled high speed voltage regulator in low ON resistance which is built-in to an ultra small USP-6C package. The output voltage for each regulator is set independently by laser trimming and selectable in 0.05V increments within a range of 0.8 to 5.0V. The EN function allows the output of each regulator to be turned off independently. In this state, with the XC6415 series, the IC turns on the internal switch located between the VOUT and the VSS pins. This short enables the electric charge at the output capacitor (CL) to be discharged via the internal auto-discharge resistance, and as a result the VOUT pin quickly returns to the VSS level. The series’ 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. Because regulator 1 and 2 are completely isolated, a cross talk between each channel, which causes a problem during load fluctuations, can be greatly reduced ■ APPLICATIONS ● Mobile phones ● Cordless phones, Wireless communication equipment ● Portable games ● Digital still cameras, Digital video cameras ● Portable audio equipment ● PDAs ■ TYPICAL APPLICATION CIRCUITS ETR0332-006a ■ FEATURES Output Current : 200mA (300mA limit, TYP.)
