The KSZ9031RNX is a completely integrated triple-speed (10Base-T/100Base-TX/1000Base-T) Ethernet physical layer transceiver for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable. Features • Single-chip 10/100/1000Mbps IEEE 802.3 compliant Ethernet transceiver • RGMII timing supports on-chip delay according to RGMII Version 2.0, with programming options for external delay and making adjustments and corrections to TX and RX timing paths • RGMII with 3.3V/2.5V/1.8V tolerant I/Os • Auto-negotiation to automatically select the highest link up speed (10/100/1000Mbps) and duplex (half/full) • On-chip termination resistors for the differential pairs • On-chip LDO controller to support single 3.3V supply operation – requires only one external FET to generate 1.2V for the core • Jumbo frame support up to 16KB • 125MHz reference clock output

The LF00 series are very Low Drop regulators available in PENTAWATT, TO-220, TO-220FP, DPAK and PPAK package and in a wide range of output voltages. The very Low Drop voltage (0.45V) and the very low quiescent current make them particularly suitable for Low Noise, Low Power applications and specially in battery powered systems. Feature summary ■ Very low dropout voltage (0.45V) ■ Very low quiescent current (TYP. 50 µA in OFF mode, 500 µA in ON mode) ■ Output current up to 500 mA ■ Logic-controlled electronic shutdown ■ Output voltages of 1.5; 1.8; 2.5; 2.7; 3; 3.3; 3.5; 4; 5; 6; 8; 8.5; 9; 12V ■ Internal current and thermal limit ■ Only 2.2 µF for stability ■ Available in ± 1% (AB) or ± 2% (C) selection at 25°C ■ Supply voltage rejection: 80db (typ.) ■ Temperature range: -40 to 125°C
