DESCRIPTION
The ZXCL series have been designed with space
sensitive systems in mind. They are available in the
ultra small SC70-5 package, which is half the size of
other SOT23 based regulators.
The devices can be used with all types of output
capacitors including low ESR ceramics and typical
dropout voltage, is only 85mV at 50mA load. Supply
current is minimised with a ground pin current of only
50 A at full 150mA load. Logic control allows the
devices to be shut down, consuming typically less than
10nA. These features make the device ideal for battery
powered applications where power economy is
critical.
For applications requiring improved performance over
alternative devices, the ZXCL is also offered in the 5 pin
SOT23 package with an industry standard pinout.
The devices feature thermal overload and over-current
protection and are available with output voltages of
2.5V, 2.6V, 2.8V, 3V, 3.3V and 4V. Other voltage options
between 1.5V and 4V can be provided. Contact Zetex
marketing for further information.
The ZXCL series are manufactured using CMOS
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.
