ADP121CB-1.2-EVALZ屬于開發(fā)板套件編程器的評估板-線性穩(wěn)壓器。由亞德諾半導體技術有限公司制造生產的ADP121CB-1.2-EVALZ評估板 - 線性穩(wěn)壓器線性穩(wěn)壓器評估板是裝有元器件的電路板，用于提供特定線性穩(wěn)壓器或器件的工作實例。每個 IC 的通道類型有單通道、雙通道、三通道和四通道，穩(wěn)壓器類型包括負可調、負固定、正可調、正固定、正負可調、正固定/可調。電壓輸出范圍為 -15V 至 56V，電流輸出范圍為 10mA 至 5A。

GENERAL DESCRIPTION

The ADP121 is a quiescent current, low dropout, linear regulator that operates from 2.3 V to 5.5 V and provides up to 150 mA of output current. The low 135 mV dropout voltage at 150 mA load improves efficiency and allows operation over a wide input voltage range. The low 30 μA of quiescent current at full load makes the ADP121 ideal for battery-operated portable equipment.

The ADP121 is available in output voltages ranging from 1.2 V to 3.3 V. The parts are optimized for stable operation with small 1 μF ceramic output capacitors. The ADP121 delivers good transient performance with minimal board area.

Short-circuit protection and thermal overload protection circuits prevent damage in adverse conditions. The ADP121 is available in a tiny 5-lead TSOT and 4-ball 0.4 mm pitch halide-free WLCSP packages and utilizes the smallest footprint solution to meet a variety of portable applications.
