ST730MR 300mA 28V Adjustable LDO SOT23-5L from ST Microelectronics

The ST730 is 300 mA LDO regulator, designed to be used in several medium voltage applications. Ultra-low quiescent current of 5 μA makes it suitable for applications permanently connected to power supply/battery. This feature is also useful when electronic modules remain permanently turned on.
The ST730 embeds protection functions, such as: current limit, short-circuit and thermal shutdown. The extended input voltage range, very low drop voltage and low quiescent current features make it suitable also for low power after-market automotive and consumer applications.

Wide input voltage range : 2.5 V to 28 V
Ultra-low quiescent current: typ. 5 μA at no-load, 10 μA max. across full temperature range, 1 μA max. in shutdown
Output current up to 300 mA
Fixed output voltage versions, starting from 1.2 V to 12 V with 100 mV step
Adjustable voltage version, starting from 1.2 V to VIN - VDROP
-40 °C to +125 °C operating temperature range

Microchip New SAMV71Q21RT, SAMRH71 Radiation-Tolerant and Radiation-Hardened Arm® MCU

Microchip introduced the space industry’s first Arm®-based microcontrollers (MCUs) that combine the low-cost and large ecosystem benefits of Commercial Off-the-Shelf (COTS) technology with space-qualified versions that have scalable levels of radiation performance. Based on the automotive-qualified SAMV71, the SAMV71Q21RT radiation-tolerant and SAMRH71 radiation-hardened MCUs implement the widely deployed Arm® Cortex®-M7 System on Chip (SoC), enabling more integration, cost reduction and higher performance in space systems. SAMV71Q21RT is the radiation tolerant version of the popular Microchip SAMV71Q21. This space-qualified version of the product adds: Ceramic & hermetic package, extended temperature range -40C to 125C, extended qualification flow according to QML-V or QML-Q space grade flow. Radiation performance for the SAMV71Q21RT: SEL LET > 60 MeV.cm2/mg (at 125C), and TID up to 20 Krad (Si). SAMRH71 is the Radiation-Hardened-By-Design (RHBD) version of the popular M

IDT New SPD Hub IC for DDR5 Server Memory Modules

IDT introduced the industry’s first integrated Serial Presence Detect (SPD), temperature sensor and control plane hub component (referred to as “SPD Hub”) developed for DDR5-based Dual In-Line Memory Modules (DIMM). The IDT® SPD Hub is designed to provide a space and power efficient solution that enables control plane operation at significantly higher speeds than previous system management buses with enhanced reliability. DDR5 memory is projected to double the bandwidth of DDR4, and as with previous generations of DDR memory, IDT’s devices are leading the market in performance and reliability. IDT’s DDR5 PMIC enables the next generation of server DIMM solutions to efficiently scale to greater performance, density and reliability while reducing overall system power. IDT’s SPD Hub significantly increases the system management bus performance by eliminating the bottlenecks of traditional system management buses. The DDR5 RCD, PMIC, SPD Hub and TS devices are used in RDIMM, LRDIM
