A
n ultralow noise, ultrahigh power supply ripple rejection (PSRR) low
dropout voltage linear regulator has been released by Linear Technology, which is a higher output current version of the 200mA LT3042 ultralow noise LDO. The LT3045’s design features ultralow spot noise of 2nV/√Hz at 10kHz and 0.8μVRMS integrated output noise across a wide
90dB out to 10kHz and high frequency PSRR exceeds 70dB out to 2.5MHz, thereby quieting noisy or high ripple input supplies. The LT3045 utilises the company’s LDO architecture - a precision current source reference followed by a high performance unity-gain buffer, resulting in virtually constant bandwidth, noise, PSRR and load regulation performance, independent of output voltage. In addition, this architecture permits paralleling of multiple devices to further decrease noise, increase output current and spread heat on a printed circuit board. The LT3045 delivers up to 500mA
output current with a 260mV dropout voltage at full load, across a wide 1.8V to 20V input voltage range. Output voltage range is 0V to 15V and output voltage tolerance is highly accurate at ±2% over line, load and temperature. The device’s wide input and output voltage ranges, high bandwidth, high PSRR and ultralow noise performance are ideal for powering noise-sensitive applications such as PLLs, VCOs, mixers, LNAs, very low noise instrumentation, high speed/high precision data converters, medical applications such as imaging and diagnostics, precision power supplies and as a post-regulator for switching supplies.

EXTERNAL POWER SUPPLIES
Mascot’s latest external power adapters come with interchangeable wall plugs and work with AC line voltages from 90V to 264V, allowing use with a wide variety of products including communication, medical, computing or office equipment deployed anywhere in the world. The wall-plug units connect via a 2-pin IEC 320 socket, which allows the additional option of using an ordinary desktop power cord. The 16-Watt Model 3523, 28-Watt Model
MEDICAL VERSIONS OF SUB-MINIATURE SNAP-IN AND NCC CONNECTORS
Medical versions of Binder’s plastic 620/720 sub- miniature and miniature snap-in and NCC (non-connected closed) connectors are now available. Manufactured from a robust polyamide 66 material that offers excellent dimensional stability and rigidity and high levels of resistance to acetate and alcohol-based disinfectants, while the bright RAL 9002 grey/white finish aids visibility of any contamination or soiling. These new connectors are ideal for all types of medical instrumentation and industrial devices that require coloured connectors. These snap-in connectors are simple, all-plastic,
modular connectors that are lightweight and compact with internal seals that provide protection to IP67 with excellent electrical characteristics. The snap-in mating provides an extremely convenient and safe connect and disconnect action. Colour coded versions in blue, green and
red are available, as are versions pre-moulded on PVC cable. The company’s NCC connectors have a design that protects the contacts to IP67 when not connected
without the need of a protective cap and are ideal for all types of portable equipment, control devices and other applications where it is an advantage to make rapid set-up changes. The efficiency of the design achieves a product life in excess of 5,000 mating cycles.

3326 and 42-Watt Model 3321 have worldwide approvals including UL certification and CE marking. The compact and lightweight units comply with EU ErP eco-design guidelines, and are also medically certified in accordance with EN 60601-1 3rd Edition. Standard output voltages for the single-output adapters give specifiers a choice of 5V, 6V, 7.5V, 9V, 12V, 15V, 18V or 24V.
