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:

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.

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.

Maximum power dissipation, for the SO8 and

SOT223 packages, is calculated assuming that the

device is mounted on a PCB measuring 2 inches

square.

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.
