Description Features
The ZXCL series have been designed with space
Low 85mV dropout at 50mA load
sensitive systems in mind. They are available in
50A ground pin current with full 150mA load
the ultra small SC70-5 package, which is half the
2.5, 2.6, 2.8, 3, & 3.3 volts output
size of SOT23 based regulators.
Very low noise, without bypass capacitor
The devices can be used with all types of output
capacitors including low ESR ceramics and
5-pin SC70 and SOT23 package
typical dropout voltage, is only 85mV at 50mA
No-load stable
load. Supply current is minimised with a ground
pin current of only 50A at full 150mA load.
Applications
Logic control allows the devices to be shut
down, consuming typically less than 10nA.
Cellular and Cordless phones
These features make the device ideal for battery
PDA
powered applications where power economy is
critical.
Hand held instruments
For applications requiring improved
Camera, Camcorder, Personal stereo
performance over alternative devices, the
PC cards
ZXCL is also offered in the 5 pin SOT23
package with an industry standard pinout.
Portable and battery-powered equipment
The devices feature thermal overload and
No-Load Stability, the ZXCL device will maintain regulation and
over-current protection and are available with is stable with no external load. e.g. CMOS RAM applacations.
