GENERAL DESCRIPTION
The ADP2300/ADP2301 are compact, constant-frequency, current-mode, step-down dc-to-dc regulators with integrated power MOSFET. The ADP2300/ADP2301 devices run from input voltages of 3.0 V to 20 V, making them suitable for a wide range of applications. A precise, low voltage internal reference makes these devices ideal for generating a regulated output voltage as low as 0.8 V, with ±2% accuracy, for up to 1.2 A load current.
