ADP2303ARDZ-R7

ADP2303 is a fixed frequency, current-mode control, step-down, dc-to-dc regulator with an integrated power MOSFET. This device has an integrated soft start circuitry to prevent a large inrush current at power-up. The power-good signal can be used to sequence devices that have an enable input. The precision enable threshold voltage allows the part to be easily sequenced from other input/output supplies. Other key features include undervoltage lockout (UVLO), overvoltage protection (OVP), thermal shutdown (TSD), and overcurrent protection (OCP). It is widely used in application such as intermediate power rail conversion, DC-to-DC point of load applications, communications and networking, industrial and instrumentation, healthcare and medical, consumer etc.
