Tiny, 1A/500mA LDO Regulators Operate from 1.425V to 3.6V and Dissipate Up to 1.9W at +70 Degrees Celsius

Maxim Integrated Products introduces the MAX15027-MAX15030 low-dropout linear regulators that operate from a 1.425V to 3.6V input voltage and deliver up to 1A (MAX15027/MAX15028) or 500mA (MAX15029/MAX15030) of output current. In addition, the MAX15028/MAX15030 feature a bias input that allows the devices to be powered from an independent supply, making them suitable for always-on power supplies in automotive applications. The bias input allows the regulator's input to reduce current to a mere 2microamps (max) during shutdown. This family of power-saving LDO regulators can dissipate up to 1.9W at +70 degrees Celsius and is ideal for a wide array of applications, including networking, storage, server, and telecom equipment.
