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.
