DEVICE DESCRIPTION
FEATURES
2.85 to 12 Volt
•
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
tolocalvoltage regulationapplications, where
problems could be encountered with
distributedsinglesourceregulation, aswellas
moregeneralvoltageregulationapplications.
Output current up to 200mA
Tight initial tolerance

Low quiescent current
-55 to 125°C temperature range
No external components
Internal thermal shutdown
Internal short circuit current limit
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.

Notes:
3. Maximum power dissipation, for the SOT223
andSO8 packages, iscalculated assumingthatthe
device is mounted on a PCB measuring 2 inches
square.
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 Tamb=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 withthe stated conditions
might exceed the power dissipation limits of the
chosen package.
4. The shut down feature of the device operates if
its temperature exceeds its design limit as might
occurduringexternalfaults,shortcircuitsetc.Ifthe
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.
