ZXCL200
ULTRA SMALL MICROPOWER SC70 2V 100mA REGULATOR
DESCRIPTION
The ZXCL200 is a very small 2 volt regulator designed
for use in low power and severely space limited
applications.
Supply current is minimised with a ground pin current
of only 40µA at full 100mA load. Logic control allows
the device to be shut down, consuming typically less
than 10nA. These features make it ideal for battery
powered applications where power economy is
critical.
The part has been designed with space sensitive
systems in mind. It is available in the ultra small SC70
package, which is half the size of other SOT23 based
regulator devices
For applicationsrequiring improved performanceover
alternative devices,theZXCL200 is also offeredin the 5
pin SOT23 package with an industry standard pinout.
The devicefeatures thermal overload and over-current
protection.
The ZXCL200 is manufactured using CMOS
processing, however advanced design techniques
mean that output noise is improved even when
compared to other bipolar devices.
