ZSAT500

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 ZSAT500 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 350mA.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.
