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 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
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.
