LM284x/LM284x-Q1 Step-Down DC/DC Regulators

Texas Instruments LM284x/LM284x-Q1 Step-Down DC/DC Regulators feature a wide input range from 4.5V-42V and are suitable for a wide range of applications, such as power conditioning from unregulated sources. These DC/DC buck regulators feature a low RDSON (0.9Ω typical) internal switch for maximum efficiency (85% typical).
