6 VOLT ENHANCED POSITIVE
LOCAL VOLTAGE REGULATOR
ISSUE 1 - AUGUST 1996
DEVICE DESCRIPTION
The ZSAT600 is an enhanced three terminal
fixed positive 6 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 62dB up to 22KHz , and
37dB up to 200KHz.
The device features internal circuit current
limit and thermal shutdown making it almost
impossible to destroy. The ZSAT600 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 450µA.
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
www.DataSheewt4Uh.ciocmh 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.

ZSAT600
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.
