ADP2300AUJZ

ANALOG DEVICES  ADP2300AUJZ  芯片, 降压稳压器, 1.2A, 6TSOT

The is a compact constant-frequency step-down DC-to-DC Regulator with integrated high-side power MOSFET. The ADP2300 device run from input voltage of 3 to 20V, making them suitable for a wide range of applications. A precise, low voltage internal reference makes this device ideal for generating a regulated output voltage as low as 0.8V, with ±2% accuracy, for up to 1.2A load current. Current-mode control provides fast and stable line and load transient performance. The ADP2300 device includes internal soft-start to prevent inrush current at power-up. Other key safety feature includes short-circuit protection, thermal shutdown TSD and input undervoltage lockout UVLO. The precision enable pin threshold voltage allows the ADP2300 to be easily sequenced from other input/output supplies. It can also be used as a programmable UVLO input by using a resistive divider.
