Start with the news release 500mA linear regulator with wide temperature range from Linear Technology, which we summarised at the time by saying "Linear Technology has widened the temperature range of its LT1763 high-voltage, 500mA linear regulator, for applications including avionics, military, industrial, automotive, RF and telecom.". Several months prior to that, we featured the news release Tantalum module provides high capacitance values from AVX: "AVX has developed a wet electrolytic tantalum module suitable for output filtering, battery holdup and energy storage and delivery in harsh environment applications. ".
 
In July 2010, we covered the news from Linear Technology - take a look at PMIC ideal for use with low-power portable devices which says: "Linear Technology has introduced a micro-power multifunction power management integrated circuit (PMIC) solution for personal navigation devices, media players and handheld medical/industrial devices.".
 
Take a look also at the news release from Pickering Interfaces, PMIC solution suits li-ion battery applications, as well as Tantalum capacitors for low-profile applications from AVX, and AVX unveils polymer tantalum capacitors from AVX.
