Outstanding Low Noise 400 mA Linear Voltage Regulator with High PSRR

Chelmsford, MA – Mar. 31, 2011 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets has introduced the HMC976LP3E, a BiCMOS linear voltage regulator which is ideal for high current, ultra low noise applications such as point-to-point microwave radio where a high data throughput demands very low power supply noise. The HMC976LP3E is also ideal for high precision, high quality test instrumentation, cellular base station infrastructure and radar or military applications

. Incorporating the HMC976LP3E regulator into VCO and PLL designs significantly improves phase noise performance and makes possible the relatively high SNR needed for signals with a dense constellation.The HMC976LP3E delivers up to 400 mA of current, a PSRR (Power Supply Rejection Ratio) of less than -60 dB at 1 kHz offset, and provides excellent rejection of any preceding switching regulator, power supply noise or any other externally generated noise.

The HMC976LP3E provides an output voltage in the 1.8 to 5 V range at 400 mA and offers extremely low output noise spectral densities of 6nV√Hz at 1 kHz offset, and 3nV√Hz at 10 kHz offset which largely surpasses the available linear voltage regulators on the market.

The HMC976LP3E is housed in 3 x 3 mm plastic leadless surface mount package and provides excellent temperature stability over the -40 °C to +85 °C temperature range. Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order.
