The ADP1761 is a high-performance, low dropout linear regulator from Analog Devices, delivering a fixed 0.9V output at up to 1A. Its ultra-low dropout voltage of 53mV at full load minimizes power loss, making it ideal for battery-powered and high-efficiency systems. With excellent power supply rejection (67dB at 10kHz), it ensures clean power for noise-sensitive applications. The compact 16-lead LFCSP package is perfect for space-constrained designs.
- Ultra-Low Dropout (53mV @ 1A): Minimizes power dissipation and extends battery life in portable applications.
- High PSRR (67dB @ 10kHz): Effectively filters switching noise, ensuring clean power for sensitive analog and RF circuits.
- Compact 3x3mm LFCSP Package: Saves critical board space in dense, high-density designs.
- Stable 1A Output: Provides reliable power for FPGAs, DSPs, and other high-current digital loads.
FPGA and DSP Core Power
Modern FPGAs and DSPs require precise, low-voltage cores (e.g., 0.9V) with high current. The ADP1761's 1A output and 0.053V dropout ensure stable operation even with tight voltage margins.
Processor I/O and Logic Supplies
Low-voltage I/O standards (LVCMOS, HSTL) benefit from the clean, regulated 0.9V rail. The high PSRR (67dB at 10kHz) filters switching noise from upstream DC-DC converters.
Noise-Sensitive Analog Circuits
For precision ADCs, DACs, and PLLs, the ADP1761 provides excellent noise isolation. Its PSRR of 35dB at 1MHz helps reject high-frequency interference.
Battery-Powered Portable Devices
The low dropout voltage maximizes battery life by allowing operation down to very low input-to-output differentials, reducing power dissipation in the regulator.
Server and Telecom Line Cards
In dense line cards, the 3x3mm LFCSP package saves board space. The 1A capability is ideal for powering auxiliary logic and interface transceivers.
Post-Regulation for Switching Supplies
Use the ADP1761 after a buck converter to provide a clean, low-noise 0.9V rail. The high PSRR attenuates ripple and switching spikes, improving system performance.
