5 VOLT ENHANCED POSITIVE
LOCAL VOLTAGE REGULATOR
ISSUE 1 - DECEMBER 1995
DEVICE DESCRIPTION
The ZSAT500 is an enhanced three terminal
fixed positive 5 volt regulator. The device is
designed particularly for use in Satellite
receiver low noise blocks where a high
degree of supply rejection is required to
extended frequencies. The device has been
improved to give superior performance with
ripple rejection of 65dB up to 22KHz , and
40dB up to 200KHz.
The device features internal circuit current
limit and thermal shutdown making it almost
impossible to destroy. The ZSAT500 shows
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.
Line and load regulation is superior to that
of other devices, with load current up to a
maximum 200mA.
For the LNB application the regulator is
offered in a surface mount SOT223 package
which permits power dissipation up to 3
watts. Additionally the device can be made
available in an SO8 surface mount package,
as well as TO92 for through hole application.
ZSAT500
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.

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 given 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.
3.
Maximum power dissipation, for the SO8 and
SOT223 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, 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.
5. HF Stability
The ZSAT500 is guaranteed stable without an
input or output capacitor. However if an output
capacitor is used then this should be a total value
of at least 100nF and should be accompanied by
an input capacitor of 200nF or greater, wired in
close proximity to the regulator if stability is to be
ensured.
