LM2585T-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2585T-12/NOPB is a Texas Instruments SIMPLE SWITCHER step-up regulator with a fixed 12 V output and 3 A maximum current. It operates from a 4 V to 40 V input range at an 115 kHz switching frequency, achieving up to 93% efficiency. The device features internal compensation for minimal external components and includes thermal shutdown and current limiting. Packaged in TO-220-5 through-hole, it supports line regulation of 100 mV and load regulation of 100 mV across a -40°C to +125°C operating temperature range.
