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.

Input to Output Diode
Increased Output current
In common with many other LDO regulators, the ZXCL
device has an inherent diode associated with the
output series pass transistor of each regulator. This
diode has its anode connected to the output and its
cathode to the input. The internal diode is normally
reverse biased, but will conduct if the output is forced
above the input by more than a VBE (approximately
0.6V). Current will then flow from Vout to Vin. For safe
operation, the maximum current in this diode should
be limited to 5mA continuous and 30mA peak. An
external schottky diode may be used to provide
protection when this condition cannot be satisfied.
Any ZXCL series device may be used in conjunction
with an external PNP transistor to boost the output
current capability. In the application circuit shown
below, a FMMT717 device is employed as the external
pass element. This SOT23 device can supply up to 2.5A
maximum current subject to the thermal dissipation
limits of the package (625mW). Alternative devices
may be used to supply higher levels of current. Note
that with this arrangement, the dropout voltage will be
increased by the VBE drop of the external device. Also,
care should be taken to protect the pass transistor in
the event of excessive output current.
