ADM7154/ADM7155 600 mA, Ultra-low Noise, High PSRR, RF Linear Regulator
Analog Devices introduces a compact linear regulator while providing excellent thermal performance
ADI's ADM7154 / ADM7155 are ultra-low noise low dropout (LDO) regulators for radio frequency (RF) signal devices. The ADM7154 / ADM7155 operate from 2.3 V to 5.5 V, provide up to 600 mA of output current, and support output voltages from 1.2 V to 3.3 V.
The LDOs achieve an output noise spectral density (NSD) of 1.5 nV / √Hz above 100 kHz, which significantly reduces voltage controlled oscillator (VCO) phase noise in point-to-point microwave radios, satellite communications, defense electronics, and other wideband applications.
Features
- Power supply rejection ration (PSRR)
- 90 dB from 1 kHz to 100 kHz
- 58 dB at 1 MHz
- VIN = 3.8 V, VOUT = 3.3 V at 600 mA
- 8-lead LFCSP and 8-lead SOIC packages
- VIN range: 2.3 V to 5.5 V
- IOUT max: 600 mA
- Fixed / adjustable output voltage range: 1.2 V to 3.3 V
- Low noise (CBYP = 1 µF)
- 0.9 µVRMS total integrated noise from 100 Hz to 100 kHz
- 1.6 µVRMS total integrated noise from 10 Hz to 100 kHz
Applications
- Regulated power noise sensitive applications
- RF mixers, phase-locked loops(PLLs)
- Voltage controlled oscillators(VCOs)
- PLLs with integrated VCOs
- Backhaul and microwave links
- Communications and infrastructure
- Cable digital-to-analog converter (DAC) drivers
