It features a low noise band-gap reference externally decoupled for best in-close noise performance. high power supply rejection Ratio (PSRR) in the MHz to 10 MHz range provides excellent rejection of preceding switching regulator noise. The four voltage outputs are ideal for frequency generation subsystems including Hittite s broad line of PLLs with Integrated VCOs.

2 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 Low Noise: 3nV/ Hz at 10 kHz, 7nV/ Hz at 1 kHzHigh power supply rejection Ratio (PSRR) 80 dB at 1 kHz, 60 dB at 1 MHzFour Voltage Outputs: VR1 @ 3V / 80 mA VR2, VR3 @ 3V / 20 mA VR4 @ / 120 mAAdjustable Outputs: to power -Down Current: <1 A16 Lead 3x3 mm SMT Package: 9mm Typical ApplicationsThe HMC860LP3E is ideal for: Test Instrumentation Military Radios, Radar and ECM Basestation Infrastructure Ultra Low Noise Frequency Generation Fractional-N Synthesizer supply Mixed-Signal Circuit SupplyElectrical Specifications, TA = +25 CParameterConditionsMinTypMaxUnitsDefaul t Output Voltage VR1, VR2, VR3 Vdd =.
