Infineon has introduced six automotive linear regulators, protected against 40 or 45V, and supplying 3.3 or 5V at up 500mA, some with enable, watchdog or reset circuits (see the table below). Picking the TLS820F3ELV50 as an example, it has an input range of 3 to 42V (45V abs max) and outputs 5V ±2% at up to 200mA. “These regulators are ...
Toshiba has announced 300mA LDOs in a 1 x 1 x 0.37mm DFN4D package. Quiescent current is typically 1.2μA with no load. They are “specifically aimed at applications powered by small-scale batteries [including] IoT modules, communications modules, wearable devices and other miniature equipment”, according to the company. There are over 30 devices spanning outputs of 0.8 to 5.0V, with an ...
Public health researchers in the US are proposing a novel approach to encourage self-regulation within the AI community, with the aim of reducing harmful outcomes without stifling innovation. “Efforts to promote ethical and trustworthy AI must go beyond what is legally mandated as the baseline for acceptable conduct,” said Jennifer Wager of Penn State University. “We can and should strive ...
Microchip has introduced a rad-tolerant 3A LDO (low drop-out regulator) for LEO (low-earth orbit) and other space appliations. MIC69303RT is available for prototype sampling in both plastic and hermetic ceramic packaging. The regulator is based on an existing COTS (commercial off-the-shelf) devices and operates from between 1.65 to 5.5V and can deliver as low as 500mV, with drop-outs as low ...
TPS7B7701-Q1, and the dual version TPS7B7702-Q1, are a pair of low-drop regulators with reverse current blocking and a wide input voltage range – that I singularly failed to notice when they were released in 2015. Reverse blocking is useful if a load needs to be supplied from an input with short interruptions in supply – most LDOs will conduct large ...
E-Peas has unveiled boost and buck energy harvesting controllers that can start up on a few hundred millivolts and provide regulated outputs as well as energy storage mediation. There are three parts: AEM00940: harvesting and storage manager with LDO Two regulated outputs Supercapacitor or battery storage Optional primary battery back-up source Boost harvester interface Harvest voltage settable across 50mV to 4.5V 380mV ...
With time on my hands, I decided to try a technique that I noticed first in a L200 voltage regulator data sheet. It is fig 25 in STM’s ‘A Designer’s guide to the L200 voltage regulator’ (ST webpage link no longer works, you will have to web-search it). Update 1 (scroll down) an alternative idea from Devgit Update 2: A ...
Wurth adds 36V input versions to its range of dc-dc converters that are pin-compatible with 78xx linear regulators
Aimed at devices that can both be charged from USB, and supply 5V through the same connector for USB on-the-go (OTG), Fairchild has released a bidirectional dc-
