Hittite Launches Industry Leading, Low Noise Voltage Regulator!
Outstanding Low Noise 400 mA Linear Voltage Regulator with High PSRR
Chelmsford, MA, 03/31/2011 – 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.
The use of the HMC976LP3E in VCOs and PLLs significantly improves phase noise performance and makes
possible the relatively high SNR needed for signals with a dense constellation. The HMC976LP3E is used in
Hittite’s PLL/VCO products and proves to be very important in preserving the excellent phase noise performance
that these products can deliver. 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. Released data sheets may be found at www.hittite.com.
