Ultra-low dropout regulators
The ZLDO regulator series
utilizes a novel approach to
achieve exceptional
performance. The devices use
the Zetex SM8 package which
has 8 pins and is based on the
SOT223 body outline.
The superior design allows the
ZLDO to take advantage of the
output device saturation voltage
to produce an exceptionally low
dropout voltage of only 30mV
with 100mA load current.
For battery applications low
power dissipation is a necessity
so the controller circuit design
has been optimized to produce
a quiescent current of 560µA,
with 1mA quiescent current at
300mA load.

A control pin is provided for
device disable and a further pin
gives a warning flag for low
supply input. Devices in the
ZLDO series are designed to
operate over the temperature
range -40 to 85°C.
