XC6204/XC6205
Series
High Speed LDO Regulators
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.

*The dissipation pad for the
USP-6B package should be
solder-plated in recommended
mount pattern and metal masking
so as to enhance mounting
strength and heal release. If the
pad needs to be connected to
other pins, it should be connected
to the V
SS
(No.5) pin.
