ADP1740ACPZ-2.5-R7

ADP1740ACPZ-2.5-R7 is a low dropout (LDO) CMOS linear regulator that operates from 1.6V to 3.6V and provides up to 2A of output current. These low VIN/VOUT LDOs are ideal for regulation of nanometre FPGA geometries operating from 2.5V down to 1.8V I/O rails and for powering core voltages down to 0.75 V. Using an advanced, proprietary architecture, the ADP1740 provide high power supply rejection ratio (PSRR) and low noise, and achieve excellent line and load transient response with only a small 4.7µF ceramic output capacitor. Application includes server computers, memory components, telecommunications equipment, network equipment, DSP/FPGA/microprocessor supplies, instrumentation equipment/data acquisition systems.
