HMC976LP3ETR Description

Short technical summary and product information.

The HMC976LP3ETR is a BiCMOS ultra-low noise linear voltage regulator designed for applications requiring excellent power supply rejection. With a high Power Supply Rejection Ratio (PSRR) in the 0.1 MHz to 10 MHz range, it effectively filters noise from preceding switching regulators or other power supply sources.

 

This regulator provides a high output current of 400mA and features an ultra-low noise characteristic of 3nV/√Hz at 10 kHz. The output voltage is adjustable from 1.8V to 5.1V, making it suitable for frequency generation subsystems, including PLLs with integrated VCOs. It can be set to 5V by grounding the HV pin and can be powered down via a TTL-compatible Enable input, drawing less than 1 µA in power-down mode.

 

The HMC976LP3E is housed in a compact 16-lead 3x3mm QFN SMT package, requiring surface mounting. It includes thermal protection and is designed to work with low ESR ceramic capacitors. Typical applications include test instrumentation, military radios, radar, ECM, basestation infrastructure, and mixed-signal circuit supply.

 

Key electrical specifications include an adjustable output voltage range of 1.8V to 5.1V, a low dropout voltage of 300mV at 400mA output, and a PSRR of up to 70dB at 1kHz. The default output voltage is typically 4.8V.
