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
L
) will be discharged via the internal auto-discharge switch, and as a result the V
OUT
pin quickly returns to the V
SS
level. The output stabilization capacitor (C
L
) 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.
