XC6204/XC6205 Series
High Speed LDO Regulatorsç Output ON-OFF Control
ETR0304_004
˙GENERAL DESCRIPTION
The XC6204/6205 series are highly precise, low noise, positive voltage LDO regulators manufactured using CMOS
processes. The series achieves high ripple rejection and low dropout and consists of a standard voltage source, an error
correction, current limiter and a phase compensation circuit plus a driver transistor.
Output voltage is selectable in 0.05V steps within a range of 0.9V ~ 6.0V.
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 also operates as a short protect for the output current limiter and the output pin.
The CE function enables the output to be turned off, resulting in greatly reduced power consumption.
