STI8035 - SUNTO

STI8035 650mA LNB-Power Supply & Control Voltage Regulator

Intended for analog and digital satellite receivers/sat-TV, sat-OC cards, the STI8035 is a monolithic voltage regulator and interface IC, packaged in eSOP8EL.

Features

 Low noise output to avoid sensitivity of Can Tuner and DISH’s LNA dropping down
 Noise < +/-80mV@350MHz BWL，
 Noise < +/-50mV@20MHz BWL
 Single chip solution on 700mVpp 22KHz EXTM with 10µ s Trise/Tfall for less Transferring noise
 LNB Voltages (2 levels: 14V and 19V) compatible with common standards, Push-pull output stage minimizes 14→ 19V and 19V→ 14V output transition times;
 External 22KHz EXTM input;
 Integrated DC/DC BOOST converter and high efficiency (typ. 90%) with integrated Power Mos-FET
 1.0MHz Switch Frequency BOOST
 Integrated low Noise Linear Regulator
 5.0V, 3.3V, 2.
