XC6415 Series

ETR0332-007

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
level. The output stabilization capacitor (C
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 game consoles

● Digital still cameras, Digital video cameras

● Portable audio equipment

● PDAs
