The HMC976LP3E by Analog Devices is a BiCMOS ultra-low noise linear voltage regulator designed for demanding applications. It provides a high output current of 400mA with a low dropout voltage of 300mV at 400mA output. The regulator boasts ultra-low noise performance of 3nV/√Hz at 10 kHz and high Power Supply Rejection Ratio (PSRR) of -60 dB at 1 kHz, making it ideal for rejecting power supply noise.
This device offers an adjustable voltage output ranging from 1.8V to 5.1V at 400mA, with a default output voltage of 4.8V. It can be set to 5V by grounding the HV pin. The HMC976LP3E includes a TTL-compatible Enable input for power-down functionality, resulting in a low power-down current of less than 1 µA. It also features thermal protection.
The HMC976LP3E is supplied in a compact 16-lead 3x3mm QFN SMT package, suitable for surface mounting. Its excellent noise and PSRR characteristics make it ideal for applications such as test instrumentation, military radios, basestation infrastructure, and frequency generation subsystems including PLLs and VCOs.
Key electrical specifications include an input voltage range of 3.3V to 5.5V for outputs above 3V, and a default input voltage range of 5.1V to 5.5V. The output voltage tolerance is ±2%. The regulator is designed to work with low ESR ceramic capacitors.
