| HMC860LP3E v00.0809 QUAD LOW NOISE HIGH PSRR LINEAR VOLTAGE REGULATOR Typical Applications The HMC860LP3E is ideal for: * Test Instrumentation * Military Radios, Radar and ECM * Basestation Infrastructure Features Ultra Low Noise: 3nV/Hz at 10 kHz, 7nV/Hz at 1 kHz High Power Supply Rejection Ratio (PSRR) 80 dB at 1 kHz, 60 dB at 1 MHz Four Voltage Outputs: VR1 @ 3V / 75 mA VR2, VR3 @ 3V / 15 mA VR4 @ 4.5V / 100 mA Adjustable Outputs: 2.5V to 5.2V Low Power-Down Current: <1 A 16 Lead 3x3 mm SMT Package: 9mm2 11 POWER CONDITIONING - SMT * Ultra Low Noise Frequency Generation * Fractional-N Synthesizer Supply * Mixed-Signal Circuit Supply Functional Diagram General Description The HMC860LP3E is a BiCMOS ultra low noise quad-output voltage regulator. It features a low noise 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 Hittite's 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.

If noise performance is not critical for a particular output, the 100nF capacitor can be omitted for the respective regulator. In this case, noise spectral density will typically increase by a factor of 20X at 10kHz. The 1F REF capacitor causes a 25ms typical turn-on start-up time. Stability Two approaches are recommended to manage the stability of the high-current regulators VR1 and VR4. If only one decoupling capacitor is used at the output, the capacitor series resistance Resr must be between 0.2 Ohm and 2 Ohm to insure stability across all loading conditions. This is shown at output VR4 in the application schematic. Note that ceramic capacitors typically have much lower Resr (as low as 0.02 Ohm at resonance) hence they will need a series resistor to insure stability. In the case when several capacitors are connected at the output (which is often the case with noise and spurious sensitive circuits), an alternate approach is to insert a small resistor in series with the load but after the 100nF feedback capacitor. This is shown by Rs1 at the VR1 output in the application schematic. The minimum resistor value is 0.1 Ohm, while the maximum value is set by the acceptable output voltage drop. Due to the lower current, regulators VR2 and VR3 do not have special stability requirements. Typical 10F ceramic capacitor ESR of 0.02 Ohm is sufficient for their stability. 11 - 8 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC860LP3E v00.0809 QUAD LOW NOISE HIGH PSRR LINEAR VOLTAGE REGULATOR Output Voltage Adjust There are several ways to adjust the output voltage for each regulator. A 5V setting for any output can be achieved by grounding the respective HVx (x=1,2,3,4) pin. Any other value requires an external resistor, connected between RDx and GND for a voltage higher than the default, or between VRx and RDx for a voltage lower than the default. The figures below show the values of the internal resistive dividers that set the default output voltage a. for 3V and b. for 4.5V and two examples of two different voltage settings: c. shows a default 3V output changed to 3.3V by connecting a 220k Ohm resistor between RDx and GND, while d. shows the same output adjusted to 2.5V by connecting a 120k Ohm resistor between VRx and RDx. The internal resistors have a temperature coefficient (TempCo) of +270ppm/C. When the default output voltage is modified by using an external resistor with a different TempCo, the temperature behavior of the respective output will differ from this specification, although the difference will likely be very small. 11 POWER CONDITIONING - SMT VRx VREF ( 1+ R1 R2 || Rx ) VRx VREF ( 1+ R1 || Rx R2 ) For VRx > VRx_default; X = 1, 2, 3, 4 VRx_default = 3V for VR1, VR2 & VR3 VRx_default = 4.5V for VR4 For VRx < VRx_default; X = 1, 2, 3, 4 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com 11 - 9 HMC860LP3E v00.0809 QUAD LOW NOISE HIGH PSRR LINEAR VOLTAGE REGULATOR 11 POWER CONDITIONING - SMT Evaluation Schematic 11 - 10 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC860LP3E v00.0809 QUAD LOW NOISE HIGH PSRR LINEAR VOLTAGE REGULATOR Evaluation PCB 11 POWER CONDITIONING - SMT List of Materials for Evaluation PCB 124352 [1] Item J7 - J20 C7 C10, C11, C13, C14, C19, C21, C23, C25 C12 C15 - C18 C20, C22, C24, C26 R13, R16, R18, R21, R29 R23, R25 R24, R26 - R28 TP1 - TP3 U1 Description 2 Pos Vertical TIN 4.7 F Capacitor, 0805 Pkg. 100 nF Capacitor, 0402 Pkg. 1.0 F Capacitor, 0603 Pkg. 10 F Capacitor, 0805 Pkg. 1000 pF Capacitor, 0402 Pkg. 1 Ohm Resistor, 0402 Pkg. 0.2 Ohm Resistor, 0402 Pkg. 0 Ohm Resistor, 0402 Pkg.
