ADP1765ACPZ-1.0-R7

ADP1765ACPZ-1.0-R7 is a low noise, low dropout (LDO) linear regulator. It is designed to operate from a single input supply with an input voltage as low as 1.10V without the requirement of an external bias supply to increase efficiency and provide up to 5A of output current (IOUT). The low 59mV typical dropout voltage at a 5A load allows the device to operate with a small headroom while maintaining regulation and providing better efficiency. The ADP1765 is optimized for stable operation with small 22µF ceramic output capacitors. The ADP1765 delivers optimal transient performance with minimal printed circuit board (PCB) area. The ADP1765 has an externally programmable soft-start time by connecting a capacitor to the SS pin. Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. Applications include field-programmable gate array (FPGA) and digital signal processor (DSP) supplies, medical and healthcare, industrial and instrumentation.
