ZXCL SERIES
MICROPOWER SC70-5/SOT353 & SOT25 LOW DROPOUT REGULATORS
Description
The ZXCL series have been designed with space sensitive
systems in mind. They are available in the ultra-small SC70-
5/SOT353 package, which is half the size of 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 minimized 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.
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 overcurrent
protection and are available with output voltages of 2.5V,
2.6V, 2.8V, 3V, 3.3V.

Notes:
1. Maximum power dissipation is calculated assuming the device is mounted on a PCB measuring 2 inches square
2. Output voltage will start to rise when V
IN
exceeds a value or approximately 1.3V. For normal operation, V
IN(min)
> V
OUT(nom)
+ 0.5V.
3. Dropout voltage is defined as the difference between V
IN
and V
O
, when V
O
has dropped 100mV below its nominal value. Nominal value of V
O
is
defined at V
IN
=V
