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.
Comprising a voltage reference, error amplifier, current limit and an enable input for output on/off control, the miniature, low-noise LDO produces a 150mA output current for a wide input voltage range, starting from as low as 1.7V and extending up to a maximum of 5.25V. The AP7340’s integrated resistor network produces fixed output voltages in 0.1V steps between 1.2V and 3.3V.
Higher than other industry solutions, the AP7340’s output voltage has an accuracy of ±1.5% over the entire operating temperature range of -40ºC to +85ºC. The AP7340 also helps to reduce product power consumption by offering a typical quiescent current of just 35µA.
The AP7340 is priced at $0.10USD each in single reel quantities of 5k.
