XC6415
Series
Dual LDO Regulator with ON/OFF Switch
ETR0332-010
■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.
