2.85 TO 12 VOLT FIXED POSITIVE

LOCAL VOLTAGE REGULATOR

ISSUE 5 - JUNE 2006

DEVICE DESCRIPTION

The ZR78L 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 ZR78L 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

ZR78L devices are completely stable with no

external components. The device will shut

down under thermal overload conditions but

as the device cools, regulation will restart.
