6 5 4 1 2 3 XC6415 Series ETR0332-010 Dual LDO Regulator with ON/OFF Switch GENERAL DESCRIPTION The XC6415 series is a highly accurate, CMOS Dual LDO voltage regulator. Performance features 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, the electric charge at the output capacitor (C ) will be discharged via the internal auto-discharge switch, and as a result the V pin quickly returns L OUT level. to the VSS 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. 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.
