Hittite Press Release - January 6, 2010
Hittite's New Power Conditioning Product Line Introduced!
High PSRR, Voltage Regulator is Ideal for Low Noise Applications
MA, 01/06/10 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions
for communication & military markets, has introduced its 24th product line, Power Conditioning, ideal for low
noise voltage regulation in automotive telematics, cellular/4G, WiMAX/4G, military and test equipment
HMC860LP3E is a Low Noise, High PSRR (Power Supply Rejection Ratio), Quad Output linear voltage regulator. It
features a low noise band gap reference externally decoupled for best in-close noise performance. High PSRR in the
0.1 MHz to 10 MHz range provides excellent rejection of preceding switching regulator noise. The HMC860LP3E
provides four voltage outputs which are adjustable from 2.5V to 5.2V, and are ideal for conditioning the DC power
supply to many low noise frequency generation subsystems including Hittite’s broad line of PLLs with Integrated
VCOs. Each of the four voltage outputs can be adjusted higher or lower than the default value by using one
external resistor, or each output can be set to 5V by grounding the appropriate pin. The HMC860LP3E regulator can
also be powered down via its TTL-compatible enable input to consume < 1 μA.
HMC860LP3E is ideal for conditioning the DC supply voltage to Hittite’s broad line of high performance
frequency generation products. The HMC860LP3E Low Noise, High PSRR Quad Output linear voltage regulator is housed
in a compact and RoHS compliant 3x3 mm QFN SMT package.
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 are available on-line at
