ADP1762ACPZ-R7

低压差稳压器 2ALowVin, VeryLow DO low noise,high PSSR

The is a 2A, low VIN, low noise, CMOS low dropout LDO linear regulator in 16 pin LFCSP package. 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 2A of output current. The low 62mV typical dropout voltage at a 2A load allows ADP1762 to operate with a small headroom while maintaining regulation and providing better efficiency. The ADP1762 is optimized for stable operation with small 10µF ceramic output capacitors. The device delivers optimal transient performance with minimal board area. It 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.
