‘Linear Regulators’
An Electronicstalk guide
Start with the news release Linear introduces H-grade switching regulator from Linear Technology, which we summarised at the time by saying "Linear Technology has announced a H-grade step-down switching regulator for load dump and cold-crank conditions commonly found in automotive applications as well as 24V industrial supplies.". Several months prior to that, we featured the news release Compact linear regulator with thermal resistance from Linear Technology: "Linear Technology has produced a wider-temperature-range version of the LT3010, a high-voltage, micropower linear regulator for avionics, military, industrial, automotive, RF and telecom applications.".
In December 2010, we covered the news from Allegro Microsystems - take a look at Sensor IC withstands harsh automotive environments which says: "Allegro Microsystems has launched the A1356, a user-programmable linear Hall-effect sensor IC with a pulse width modulated (PWM) output for automotive gear and clutch detection and position sensing.".
Take a look also at the news release from Diodes Incorporated, Driver controller for illumination and signage, as well as CMOS LDO regulators for low-power applications from Torex Semiconductor, and Synchronous buck regulator for POL applications from Semtech.
