Dual 500mA μPower LDO
May 01, 2012 // Molly Zhu, Linear Technology // 0 commentsDownload White Paper 302Ko
The LT3029 integrates two independent 500mA monolithic LDOs in a tiny 16-lead MSOP or 4mm × 3mm × 0.75mm DFN package. Both regulators have a wide 1.8V to 20V input voltage range with a 300mV dropout voltage at full load. The output voltage is adjustable down to the 1.215V reference voltage. With an external bypass capacitor, the output voltage noise is less than 20μVRMS. A complete power supply requires only a minimum 3.3μF ceramic output capacitor for each channel to be stable.

The SoCKIT evaluation kit is Arrow's latest development tool, featuring an Altera Cyclone V SoC with a dual-core ARM Cortex-A9 MPCore processor integrated within its 28nm FPGA fabric.
Altera SoCs allow embedded system developers to differentiate their end product with customized hardware and software, and extend the product lifecycle through hardware and software updates in the field. This month, Arrow Electronics is giving away five SoCKIT evaluation kits featuring Altera’s ARM-Based SoCs, worth €249 each, together with the free entrance to one of Arrow’s SoC workshops organized throughout Europe.
And the winners are...
In our previous reader offer, Freescale Semiconductor was giving away five IMX6Q, Sabre-lite kits, worth £128.06 each.
Lucky winners include Mr. X. Salada Sole from the UK, Mrs A. Peric from Germany, Mr Z. Janosy from Hungary, Mr D. Gacina from Croatia and Mr B. Boris from France. All should be receiving their packages soon. Let's wish them some interesting findings with their projects.
