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. There are two frequency options： the ADP2300 runs at 700 kHz， and the ADP2301 runs at 1.4 MHz. These options allow users to make decisions based on the trade-off between efficiency and total solution size. Current-mode control provides fast and stable line and load transient performance. The ADP2300/ADP2301 devices include internal soft start to prevent inrush current at power-up. Other key safety features include short-circuit protection， thermal shutdown （TSD）， and input undervoltage lockout （UVLO）。 The precision enable pin threshold voltage allows the ADP2300/ADP2301 to be easily sequenced from other input/ output supplies. It can also be used as a programmable UVLO input by using a resistive divider. The ADP2300/ADP2301 are available in a 6-lead TSOT package and are rated for the −40°C to +125°C junction temperature range.
