2.85 TO 12 VOLT FIXED POSITIVE
LOCAL VOLTAGE REGULATOR
ZSR
SERIES
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 350µA. 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.

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
=125°C.
amb
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.
) 200mA
o
Power Dissipation (T
amb
=25°C)
SOT223 2W(Note 3)
TO92 600mW
S08 780mW(Note 3)
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.
