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.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to
absolute maximum rating conditions for extended periods
may affect device reliability. The absolute maximum ratings
apply individually only and not in combination.
