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.
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.
FEATURES
• 5-pin SC70 package for the ultimate in space
saving
• 5-pin SOT23 industry standard pinout
