NEW PRODUCT RELEASE FOR IMMEDIATE RELEASE CONTACT: Beth McGreevy MarCom Manager (978) 250-3343 x1117 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.
