LDO linear regulators launched by Maxim
A Maxim Integrated Products product story
Edited by the Electronicstalk editorial team Jul 8, 2009
Maxim Integrated Products has introduced the MAX15027-MAX15030 low-dropout (LDO) linear regulators that operate from a 1.425V-3.6V input voltage.
The regulators 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 2microamps (maximum) during shutdown.
This family of power-saving LDO regulators can dissipate up to 1.9W at +70C and is ideal for an array of applications, including networking, storage, server, and telecom equipment.
The MAX15027-MAX15030 offer high performance with +/- two per cent accuracy over line, load, and temperature; as well as a dropout voltage as low as 75mV (MAX15027/MAX15028) or 40mV (MAX15029/MAX15030) under full load.
Other features include a capacitor-adjustable soft-start input, an enable input, and an adjustable feedback input to set the output voltage from 0.5-3.3V.
These regulators are offered in a 3 x 3mm, thermally enhanced, 10-pin TDFN package and are fully specified over the -40C to +125C automotive temperature range.
