The ADP2302 / ADP2303 are fixed frequency, current-mode control, step-down, dc-to-dc regulators with an integrated power MOSFET. The ADP2302 / ADP2303 can run from an input voltage of 3.0 V to 20 V, which makes them suitable for a wide range of applications. The output voltage of the ADP2302 / ADP2303 can be down to 0.8 V for the adjustable version, while the fixed output version is available in preset output voltage options of 5.0 V, 3.3 V, and 2.5 V. The 700 kHz operating frequency allows small inductor and ceramic capacitors to be used, providing a compact solution. Current mode control provides fast and stable line and load transient performance. The ADP2302 / ADP2303 have 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).

The ADP2302/ADP2303 devices are available in the 8-lead, SOIC package with exposed paddle and are rated for the −40oC to +125oC junction temperature range.

Product Detail

The ADP2302/ADP2303 are 2 A/3 A, 20 V, nonsynchronous step-down, dc-to-dc regulators with an integrated power MOSFET in a SOIC package with an exposed paddle. The ADP2302/ ADP2303 evaluation boards are complete buck regulator solutions that allow users to evaluate the performance of the regulators.


The ADP2302/ADP2303 integrated soft-start circuitry prevents inrush current at power-up. The power-good output indicates that the output voltage is regulated within tolerance, and it can be used to sequence devices that have an enable input. The precision enable feature allows the part to be easily sequenced from external supplies. Other key features include undervoltage lockout (UVLO), output overvoltage protection (OVP), thermal shutdown (TSD), and overcurrent protection (OCP).
