2.85 TO 12 VOLT FIXED POSITIVE
LOCAL VOLTAGE REGULATOR
ISSUE 3 - NOVEMBER 1997
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.

3.
Maximum power dissipation, for the SOT223
and SO8 packages, is calculated assuming that the
device is mounted on a PCB measuring 2 inches
square.
4.
The shut down feature of the device operates if its
temperature exceeds its design limit as might occur
during external faults, short circuits etc. If the regulator
is supplied from an inductive source then a large
voltage transient, on the regulator input, can result
should the shut down circuit operate. It is advised that
a capacitor (1µF or greater) should be applied across
the regulator input to ensure that the maximum
voltage rating of the device is not exceeded under
shutdown conditions.
ELECTRICAL CHARACTERISTICS
Notes:
1.
The maximum operating input voltage and
output current of the device will be governed by
the maximum power dissipation of the selected
package. Maximum package power dissipation is
specified at 25 °C and must be linearly derated to
zero at T
amb
=125°C.
2.
The following data represents pulse test
conditions with junction temperatures as indicated
at the initiation of the test. Continuous operation
of the devices with the stated conditions might
exceed the power dissipation limits of the chosen
package.
