XC6204 Series
(Can be used with low ESR Capacitor Compatible. ON OFF Switch)
High Speed LDO Regulators
General Description
Features
The XC6204 series are highly precise, low noise, positive volt-
age LDO regulators manufactured using CMOS processes.
The series achieves high ripple rejection and low dropout and
consists of a standard voltage source, an error amplifier, a
current limiter, a phase compensation circuit and a driver tran
sistor.
Output voltage is selectable in 50mV increments within a
range of 1.8V to 6.0V.
The series is also compatible with low ESR ceramic capaci-
tors 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.
