ANALOG DEVICES ADP1761ACPZ-1.3-R7 LDO Voltage Regulator, Fixed, 1.1 to 1.98V in, 30mV Drop, 1.3V / 1A Out, LFCSP-EP-16, -40 to 125 °C

ADP1761ACPZ-1.3-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 1A of output current. The low 30mV typical dropout voltage at a 1A load allows the device to operate with a small headroom while maintaining regulation and providing better efficiency. The ADP1761 is optimized for stable operation with small 10µF ceramic output capacitors. The ADP1761 delivers optimal transient performance with minimal board area. The ADP1761 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. Application includes field-programmable gate array (FPGA) and digital signal processor (DSP) supplies, medical and healthcare, industrial and instrumentation, automotive.
