The ADP2303ARDZ-5.0-R7 from Analog Devices is a fixed-frequency, current-mode control, step-down DC-to-DC regulator. It is designed to operate from an input voltage range of 3.0 V to 20 V and can deliver a maximum load current of 3 A.
This regulator features a 700 kHz switching frequency, which allows for the use of small inductors and ceramic capacitors, enabling a compact solution. The output voltage is fixed at 5.0 V with an accuracy of ±1.5% over temperature. Key integrated features include a high-side MOSFET, bootstrap diode, internal compensation, and soft start circuitry to manage inrush current.
Additional protective features include undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown (TSD). The device is supplied in an 8-lead SOIC package with an exposed paddle, suitable for surface mount applications. The power-good output signal can be utilized for device sequencing.
This regulator is well-suited for intermediate power rail conversion and DC-to-DC point-of-load applications in communications, networking, industrial, instrumentation, healthcare, and consumer electronics.
