Overview
ZXCL250 ZXCL260 ZXCL280 ZXCL300 ZXCL330 ZXCL400 ULTRA SMALL MICROPOWER SC70 LOW DROPOUT REGULATORS DESCRIPTION The ZXCL series are very small low dropout regulators designed for use in low power and severely space limited applications.
The devices operate with a low dropout voltage, typically of only 85mV at 50mA load.
Supply current is minimised with a ground pin current of only 50µA 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.
The parts have been designed with space sensitive systems in mind.
They are available in the ultra small SC70 package, which is half the size of other SOT23 based regulator devices.
FEATURES 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.

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.
