TMI8037 500mA LNB-Power Supply & Control Voltage Regulator

Intended for analog and digital satellite receivers/sat-TV, sat-OC cards, the TMI8037 is a monolithic voltage regulator and interface IC, packaged in ESOP8, specifically designed to provide the 14V/19V power supply with high efficiency and the 22kHz TONE signaling to the LNB downconverter in the ant.

TMI8037 Features

* High Efficiency: Up to 90%

* Low noise output to avoid sensitivity of Can Tuner and DISH’s LNA dropping down

* Noise 40mV@20MHz BWL

* Single chip solution on 650mVpp

* 22kHz TONE with 10µs Trise/Tfall for less Transferring noise

* LNB Voltages (2 levels: 14V and 19V) compat
