ADP161屬于集成電路（IC）的穩(wěn)壓器-DC-DC開關穩(wěn)壓器。由亞德諾半導體技術有限公司制造生產的ADP161穩(wěn)壓器 - DC-DC 開關穩(wěn)壓器DC-DC 開關穩(wěn)壓器 PMIC（電源管理集成電路）產品族中的產品是元器件級設備，用于需要穩(wěn)定 DC 輸入電壓和/或將其轉換為不同幅度的輸出電壓的應用。這些器件與稱為“控制器”PMIC 的類似產品的區(qū)別在于集成了主開關元件，設備提供的電力會通過該元件。

GENERAL DESCRIPTION

The ADP160/ADP161/ADP162/ADP163 are ultralow quiescent current, low dropout, linear regulators that operate from 2.2 V to 5.5 V and provide up to 150 mA of output current. The low

195 mV dropout vol tage at 150 mA load improves efficiency and allows operation over a wide input voltage range.

The ADP16x are specifically designed for stable operation with a tiny 1 μF ± 30 ceramic input and output capacitors to meet the requirements of high performance, space-constrained

applications.

The ADP160 is available in 15 fixed output voltage options, ranging from 1.2 V to 4.2 V . The ADP160/ADP161 also include a switched resistor to discharge the output automatically when the LDO is disabled. The ADP162 is identical to the ADP160 but does not include the output discharge function.
