The ADP2301AUJZ-R7 is a Non-synchronous Step-down Regulator with integrated power MOSFET. It runs from input voltages of 3.0 to 20V, making it 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 0.8V, with ±2% accuracy, for up to 1.2A load current. The ADP2301 runs at 1.4MHz. Current-mode control provides fast and stable line and load transient performance. The ADP2301 devices include internal soft start to prevent inrush current at power-up. Other safety key features include short-circuit protection, thermal shutdown (TSD) and input under-voltage lockout (UVLO). The precision enable pin threshold voltage allows the 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.
