HMC860LP3E v01.0811 QUAD LOW NOISE HIGH PSRR LINEAR VOLTAGE REGULATOR Typical Applications Features The HMC860LP3E is ideal for: Ultra Low Noise: 3nV/Hz at 10 kHz, 7nV/Hz at 1 kHz Test Instrumentation High Power Supply Rejection Ratio (PSRR) Military Radios, Radar and ECM 80 dB at 1 kHz, 60 dB at 1 MHz Basestation Infrastructure Four Voltage Outputs: VR1 3V / 80 mA Ultra Low Noise Frequency Generation VR2, VR3 3V / 20 mA Fractional-N Synthesizer Supply VR4 4.5V / 120 mA Mixed-Signal Circuit Supply Adjustable Outputs: 2.5V to 5.2V Low Power-Down Current: <1 A 16 Lead 3x3 mm SMT Package: 9mm Functional Diagram General Description The HMC860LP3E is a BiCMOS ultra low noise quad-output voltage regulator. It features a low noise 9 band-gap reference externally decoupled for best in-close noise performance. High Power Supply Rejection Ratio (PSRR) in the 0.1 MHz to 10 MHz range provides excellent rejection of preceding switching regulator noise. The four voltage outputs are ideal for frequency generation subsystems including Hittites broad line of PLLs with Integrated VCOs. Each output voltage can be adjusted higher or lower than the default value by using one external resistor. Each output can be set to 5V by grounding the corresponding HV pin. The regulator can be powered down by the TTL-compatible Enable input. The HMC860LP3E is housed in a 3x3mm QFN SMT package.
