Adjustable 500mA LDO voltage regulator operates from -55 up to +225°C
February 29, 2012 // Julien Happich
Cissoid introduced Vega, a low dropout, linear, voltage regulator for embedded power supply needs in applications that must sustain high-temperature, harsh environments or that simply require extended lifetimes. The CHT-Vega voltage regulator delivers a regulated output with up to 500mA from a standard 5V ±10% voltage input.
Output voltage can be adjusted anywhere between 1.2V and 3.3V. It is packaged in a tiny SMD ceramic package TDFP 5x5.5mm, guaranteed for operation from -55°C up to +225°C. Total output voltage accuracy under all operating conditions including load, line and temperature variations is guaranteed to be better than ±5%. A special care has been taken of optimizing the response to line and load transients, which makes the chip suitable to supply high temperature microprocessors and memories. The regulator is self-protected with a built-in over-current limitation combined with a thermal protection which becomes effective above 250°C. The circuit typically requires an external 2.2µF capacitor and a 2-resistor bridge for feedback (output voltage setting).Visit Cissoid at www.cissoid.com

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
