GENERAL DESCRIPTION
ETR0347-006
0.6μA Ultra Low Power Consumption Small Voltage Regulator (C
L
Capacitor-Less)
The XC6504 series is a highly accurate CMOS voltage regulator that achieves very low supply current operation of 0.6μA.
Even output current is 1μA (when light load), the XC6504 can provide high accurate outputs, which is ideally suited for the
applications to draw less output current. The usage of super small package USPN-4B02 (0.75 x 0.95mm) and the advantage
of capacitor-less stable operation can contribute the board space saving outstandingly. The IC consists of a reference voltage
source, an error amplifier, a driver transistor, over-current protection circuit, and a phase compensation circuit.
The device is compatible with a low ESR ceramic output capacitor C
L
. Moreover, the device can provide stable output even
without a C
L
output capacitor because of the excellent internal phase compensation.
Output voltage is fixed internally by laser trimming technology and can be selectable in 0.1V increments within the range of
1.1V to 5.0V. The CE function enables the device to be put into standby mode by inputting a low level signal to the CE pin
thereby reducing current consumption to less than 0.1μA. In the standby mode, if a C
L
output capacitor is used, the electric
charge stored at C
L
can be discharged via the internal switch and as a result, the V
OUT
pin quickly returns to the V
SS
level.

■PIN
CONFIGURATION
*The dissipation pad for the USPQ-4B04 package should be solder-plated in reference mount pattern and metal masking
so as to enhance mounting strength and heat release.
If the pad needs to be connected to other pins, it should be connected to the V
SS
(No. 2) pin.
