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
other 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.
FEATURES
5-pin SC70 package for the ultimate in space
saving
5-pin SOT23 industry standard pinout
Can be used with all types of output capacitor
Low 85mV dropout at 50mA load
50 A ground pin current with full 150mA load
Typically less than 10nA ground pin current on
shutdown
2.5, 2.6, 2.8, 3, 3.3 and 4 volts output
Very low noise, without bypass capacitor
Thermal overload and over-current protection
-40 to +85C operating temperature range
No-load stable
PACKAGE FOOTPRINT
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.
APPLICATIONS
Cellular and Cordless phones
Palmtop and laptop computers
PDA
Hand held instruments
Camera, Camcorder, Personal Stereo
PCMCIA cards
Portable and Battery-powered equipment
No-Load Stability, the ZXCL device will maintain regulation and is stable
with no external load. e.g. CMOS RAM applacations.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
conditions for extended periods may affect device reliability.

Device testing is performed at T
A
=25 C. Device thermal performance is guaranteed by design.
Note1: Maximum power dissipation is calculated assuming the device is mounted on a PCB measuring 2 inches
square
Note 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.
Note 3: Dropout voltage is defined as the difference between V
IN
and V

, when V
O
has dropped 100mV below
its nominal value. Nominal value of V
O
is defined at V
