XC6231
Series
１0V
Input, 500mA, High Speed LDO Regulators
ETR03090-001
■GENERAL
DESCRIPTION
XC6231 series are highly precise, low noise, positive voltage LDO regulators which features high ripple rejection and low
dropout. Output voltage is selectable within a range of 0.9V ~ 5.5V. The series is also compatible with low ESR ceramic
capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent
transient response of the series. The current limiter’s foldback circuit operates as a short-circuit protection as well as the
output current limiter for the output pin.
