XC6415
Series
Dual LDO Regulators with ON/OFF Switch
ETR0332-006a
■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 V
OUT
and the V
SS
pins. This short enables the electric charge at the output
capacitor (C
L
) to be discharged via the internal auto-discharge resistance, and as a result the V
OUT
pin quickly returns to the V
SS
level. The series’ 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
