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 applications requiring improved performance over
alternative devices, the ZXCL200 is also offered in the 5
pin SOT23 package with an industry standard pinout.
The device features thermal overload and over-current
protection.

processing, however advanced design techniques
mean that output noise is improved even when
compared to other bipolar devices.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum conditions for extended periods may affect device reliability.
