Toshiba has announced a family of CMOS low drop-out (LDO) regulators. Called TCR4DG, they have an on-off control input and come in in fixed output voltages between 1.0 and 4.5V, at up to 420mA. Typical drop-out is 193mV (420mA, 3.3Vout). Low output noise voltage is claimed, and as befitting a Japanese company, the claim is backed up by figures: Vnoise ...

Gallium oxide power device firm gets £5m in second-round funding
Japanese gallium oxide power device start-up Flosfia has raised Y750m (£5m) in series B funding. The firm, a spin-out from the Kyoto University, is aiming to commercialise crystalline α-Ga2O3 (corundum/sapphire/ruby structure) in power transistors and Schottky diodes – with the intention of manufacturing 600V TO-220 diodes in 2018 to compete against silicon carbide power devices. Its second intellectual property is ...
CES: ON Semi saluted for Bluetooth hearing aid device
ON Semiconductor has picked up two consumer semiconductor awards in the run up to CES 2017 which takes place in Las Vegas next month. The Consumer Technology Association (CTA) recognised On Semiconductor’s Ezairo 7150 SL audio processor for hearing aids along with its Smart Passive Sensor (SPS). Ezairo 7150 SL is described as “an open-programmable digital signal processing (DSP)-based hybrid, which enables wireless connectivity in hearing aids ...
TCXO achieves ±0.5ppm over -40 to +85°C
IQD’s new analogue ASIC-based temperature-compensated crystal oscillator (TCXO) is tested using one frequency reading every two degrees centigrade over the full operating temperature range. “This, combined with a high order compensation circuit, delivers a frequency stability as tight as ±0.5ppm over -40 to +85°C,” said the firm. Called IQXT-274, it comes in a 3.2 x 2.5 x 1.1mm hermetically sealed ...
Electronica: Nano-power and precision from one op-amp
Texas Instruments has introduced what it claims are the industry’s first precision nano-power op amps. LPV811 consumes 450nA (typ) and offers 370µV (max, +/-60μV typ) offset, while offset in the dual LPV812 is 300µV. If more offset can be tolerated, there are even lower current versions – see below. The op-amp family is aimed at battery-powered sensors in building automation, ...
E2V K-Band DAC outputs 26.5GHz
E2V is claiming a world first with a DAC that can generate K-Band (18-27GHz) signals directly, without a mixer. Called EV12DS460, conversion is 12bit at at 6Gsample/s guaranteed, with operation possible up to 7Gsample/s. “Removing up-conversion stages in our customers’ systems operating up to K-band will help them simplify system design,” said company v-p semiconductors Laurent Monge. 7.5 GHz of analogue output ...
Electronica 2016: Pickering switches to 2-pole reed relays
Pickering Electronics will demonstrate its two pole reed relays for high density designs at the Electronica exhibition in Munich next week (8 – 11 November). The series 115, 2 Form A relays can switch up to 15W, 1A and measuring 4mm x 10mm, the two-pole relay is only 50% larger than the single pole version. Two switch types are available. Both types have ...
