Regulator ensures high-quality supply for analog circuits
The new AP7340 low-dropout regulator from Diodes Inc is designed to provide a high-quality supply for analog circuits in noise-sensitive audio, video and RF applications due to a high PSRR of 75dB at 1kHz, and a low-noise performance of 60µVrms over the 10Hz to 100kHz range. Coming in a 1.0mm x 1.0mm DFN1010-4 package, the AP7340 suits the highest density portable product designs.
Multicell battery gas guage measures to within 1% accuracy
Enabling direct measurements of 3.6V to 20V battery stacks, Linear have today announced the LTC2943 multicell battery gas gauge. The LTC2943 accurately assess battery SoC, due to being able to measure charge, voltage, current and temperature to within 1% accuracy. Total current consumption is minimized and measurement accuracy is preserved with the LTC2943 requiring no level shifting circuitry on the supply and measurement pins in ord...
IR's µIPM power modules offer 60% smaller footprint
