Microchip LDO voltage-regulator family with low noise and high PSRR

Leave a Comment / Tech News Updates / By

Microchip Technology Inc., announced the MCP1755 and MCP1755S family of CMOS Low-Dropout (LDO) voltage regulators.  These LDOs have an input voltage range of 3.6-16V and deliver an output current of 300 mA at output voltages of 1.8-5.5V, while consuming only 68 µA of quiescent current (typical).  Additionally, the LDOs have a shutdown pin, enabling them …

A bright idea: Tiny injectable LEDs help neuroscientists study the brain

Leave a Comment / Tech News Updates / By

A thin plastic ribbon printed with advanced electronics is threaded through the eye of an ordinary sewing needle. The device, containing LEDs, electrodes and sensors, can be injected into the brain or other organs. Researchers at the University of Illinois at Urbana-Champaign and Washington University in St. Louis developed ultrathin, flexible optoelectronic devices – including …

Generating High DC Output Voltage from Low Input Supply

Leave a Comment / Tech News Updates / By

Whether for driving white LED backlights or powering RF and analog circuits, laptops, tablets and other mobile devices often require voltages that are much higher than the input supply voltage. Consequently, step-up or boost DC/DC converters generate output voltages that are several times the input to serve a variety of circuits and functions in these …

Switches MEC Unimec switch in up to eight ways

Leave a Comment / Tech News Updates / By

If we design a device with push buttons, it is usually advantageous when we can use the same push-buttons, independently on whether we use them for switch-on, switch-off, change-over,… Moreover, at a modification of a given device, a possibility to change the function of a given push-button without its exchange is often highly welcome. Unimec …
