The ADP1761WACPZ-R7 from Analog Devices is a high-performance, low dropout linear regulator delivering a fixed 1.5V output at up to 1A. Its ultra-low dropout voltage of just 53mV at full load enables efficient operation from low input voltages, starting at 0.5V. With excellent PSRR of 67dB at 10kHz and 35dB at 1MHz, this regulator provides clean, stable power for noise-sensitive applications. The compact 16-lead LFCSP package is ideal for space-constrained designs.
- Ultra-Low Dropout (53mV @ 1A): Maximizes efficiency and allows operation from very low input voltages, reducing power dissipation.
- High PSRR (67dB @ 10kHz): Effectively filters power supply noise, ensuring clean output for sensitive analog and RF circuits.
- Wide Input Range (from 0.5V): Supports operation from deeply discharged batteries or low-voltage rails.
- Compact 3x3mm LFCSP Package: Saves critical board space in portable and high-density designs.
FPGA and DSP Core Power
Modern FPGAs and DSPs require precise 1.5V core rails with high transient response. The ADP1761's low dropout of 53mV at 1A ensures stable operation even with tight voltage margins, while its high PSRR (67dB at 10kHz) rejects switching noise from upstream DC-DC converters.
High-Speed ADC/DAC Reference Supplies
Data converters demand ultra-clean supply rails. The ADP1761's PSRR of 35dB at 1MHz effectively filters high-frequency noise, preserving signal integrity in communication and instrumentation systems.
Battery-Powered Portable Devices
With an input range starting at 0.5V, this LDO can operate from deeply discharged batteries or single-cell Li-ion packs. The low quiescent current of 8mA helps extend battery life in handheld medical and industrial devices.
Noise-Sensitive RF Transceivers
RF circuits are susceptible to power supply noise. The ADP1761's excellent high-frequency PSRR (35dB at 1MHz) minimizes spurious emissions, making it ideal for powering VCOs, PLLs, and RF front-ends.
Automotive ECU Power Conditioning
The automotive-qualified version (W suffix) is designed for harsh environments. It provides clean 1.5V power to microcontrollers and sensors in engine control units, ensuring reliable operation under temperature extremes.
Server and Storage Power Sequencing
In data center equipment, the ADP1761 can power low-voltage logic rails with minimal heat dissipation. Its small 3x3mm LFCSP package saves board space in dense server motherboards.
