HMC860LP3E Linear Voltage Regulator

Analog Devices, a world-class supplier of complete MMIC based solutions for communication and military markets, has introduced the Power Conditioning product line, ideal for low noise voltage regulation in automotive telematics, cellular/4G, WiMAX/4G, military, and test equipment applications.

The 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, adjustable from 2.5 V to 5.2 V, and is 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 5 V by grounding the appropriate pin. The HMC860LP3E regulator can also be powered down via its TTL-compatible enable input to enable power consumption below 1 μA.

The 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, RoHS compliant 3 x 3 mm QFN SMT package.
