ADI ADP2303ARDZ-R7

降压降压3V20V3A

Overview

The ADP2302/ADP2303ARDZ-2.5-R7 are fixed frequency, current-mode control, step-down, dc-to-dc regulators with an integratedpower MOSFET. The ADP2302/ADP2303ARDZ-2.5-R7 can run from an input voltage of 3.0 V to 20 V, which makes them suitable for awide range of applications. The output voltage of the ADP2302/ADP2303ARDZ-2.5-R7 can be down to 0.8 V for the adjustable version, whilethe fixed output version is available in preset output voltage options of 5.0 V, 3.3 V, and 2.5 V. The 700 kHz operatingfrequency allows small inductor and ceramic capacitors to be used, providing a compact solution. Current mode controlprovides fast and stable line and load transient performance. The ADP2302/ADP2303ARDZ-2.5-R7 have integrated soft start circuitry toprevent 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 keyfeatures include undervoltage lockout (UVLO), overvoltage protection (OVP), thermal shutdown (TSD), and overcurrentprotection (OCP).

The ADP2302/ADP2303ARDZ-2.5-R7 devices are available in the 8-lead, SOIC package with exposed paddle and are rated for the −40oCto +125oC junction temperature range.
