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.
