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.ApplicationsTest InstrumentationMilitary Radios, Radar and ECMBasestation InfrastructureUltra Low Noise Frequency GenerationFractional-N Synthesizer SupplyMixed-Signal Circuit Supply
