DEVICE DESCRIPTION
The ZS¤D5030 dual fixed positive voltage
regulators feature internal circuit current limit
and thermal shutdown making the devices
almost impossible to destroy.
The devices are available in Zetex small outline
SM8 package, ideal for applications where
space saving is important. Two configurations
are available - common and isolated - as
represented in the schematic diagrams below.
The devices feature output voltages of 5 and 3
volts each capable of delivering up to 200mA.
The SM8 package allows up to 2.25W power
dissipation for each regulator.
The devices are suited to local voltage
regulation applications, where problems could
be encountered with distributed single source
regulation, as well as more general voltage
regulation applications.
The ZS¤D5030 devices show performance
characteristics superior to other local voltage
regulators. The initial output voltage is
maintained to within 2.5% with a quiescent
current of typically 350
μ
A. Output voltage
change with input voltage and load current is
much lower than competitive devices. The
ZS¤D5030 devices are completely stable with
no external components. The devices will shut
down under thermal overload conditions but
as the device cools, regulation will restart until
thermal overload reoccurs.
