DEVICE DESCRIPTION

The ZSR Series three terminal fixed positive voltage

regulators feature internal circuit current limit and

thermal shutdown making the devices difficult to

destroy. The circuit design allows creation of any

custom voltage in the range 2.85 to 12 volts. The

devices are available in a small outline surface mount

package, ideal for applications where space saving is

important, as well as through hole TO92 style

packaging. 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 ZSR Series 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

µA. Output voltage

change, with input voltage and load current, is much

lower than competitive devices. The ZSR devices are

completely stable with no external components.
