onsemi NCV59745 Linear Voltage Regulator
onsemi NCV59745 Linear Voltage Regulator is a 3A LDO regulator with ultra-low noise and 115mV typical voltage dropped at full load current. The LDO regulator contains fixed output voltages with high accuracy and broad bandwidth high PSRR. This feature makes the LDO ideal for powering noise-sensitive high-speed communication devices, high-end FPGAs, and microprocessors. onsemi NCV59745 is offered in a QFNW20 (4mm × 4mm) package. Typical applications include high-speed analog voltage-controlled oscillators (VCOs), digital-to-analog converters (DACs), analog-to-digital converters (ADCs), FPGAs, DSPs, SerDes, imaging sensors, ASICs, automotive, telecom, industrial equipment, and point-of-load regulation.
