Functional Diagram

General Description

The HMC976LP3E is a BiCMOS ultra low noise

linear voltage regulator. The high Power Supply

Rejection Ratio (PSRR) in the 0.1 MHz to 10 MHz

range provides excellent rejection of any preceding

switching regulator or other power supply noise.

The voltage output is ideal for frequency generation

subsystems including Hittite’s broad line of PLLs with

integrated VCOs.

The output voltage can be adjusted lower than the

default value by using one external resistor. The output

can be set to 5V by grounding the HV pin. The regulator

can be powered down by the TTL-compatible Enable

input. The HMC976LP3E is housed in a 3x3mm QFN

SMT package.
