LDO regulator limits shutdown current to 2 microamps

MAX15027-MAX15030 low-dropout (LDO) linear regulators operate from a 1.425 to 3.6 V input voltage and deliver up to 1 A (MAX15027/MAX15028) or 500 mA (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 2 microamps (max) during shutdown. This family of power-saving LDO regulators can dissipate up to 1.9 W at 70° C and is suitable for a wide range of applications, including networking, storage, server, and telecom equipment.

The MAX15027-MAX15030 offer high performance with ±2% accuracy over line, load, and temperature, as well as a dropout voltage as low as 75 mV (MAX15027/MAX15028) or 40 mV (MAX15029/MAX15030) under full load conditions. Other features include a capacitor-adjustable soft-start input, enable input, and adjustable feedback input to set the output voltage from 0.5 to 3.3V.

Regulators are offered in a 3 x 3 mm, thermally enhanced, 10-pin TDFN package and are fully specified over the -40° to 125° C automotive temperature range.
