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 40
A 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
FEATURES
5-pin SC70 package for the ultimate in space
saving
5-pin SOT23 industry standard pinout
40
A ground pin current with full 100mA load
Typically less than 10nA ground pin current on
shutdown
2 volt output
Very low noise, without bypass capacitor
Thermal overload and over-current protection
-40 to +85C operating temperature range
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.

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.
