2.85 TO 12 VOLT FIXED POSITIVE
LOCAL VOLTAGE REGULATOR
ISSUE 3 - DECEMBER 2001
ZR78L
SERIES
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 350µA. 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.
