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.
