矽源特ME1117/矽源特MET1117 700mA可调电压高速LDO稳压器MET117系列

矽源特ME1117/矽源特MET1117 General Description:

【资料图】

矽源特MET1117系列是高精度、低噪声的LDO稳压器，能够提供超过700mA的输出电流，700mA时的最大压降为1.5 V。该系列包含六个固定输出电压，分别为1.2 V、1.8 V、2.5 V、3.3 V和5.0 V，它们没有维持调节的最低负载要求。

还包括一个可调输出版本，可通过两个外部电阻器从1.25 V编程到20 V。片上微调将参考/输出电压调整到±2.0%的精度范围内。内部保护功能包括输出电流限制、安全工作区补偿和热关机。矽源特MET1117系列可在高达20 V的输入下工作。设备有SOT223、TO252-2L。

The 矽源特MET1117 series are highly accurate, low noise,LDO Voltage Regulators that are capable of providing an output current that is in excess of 700mA with a maximum dropout voltage of 1.5 V at 700mA. This series contains six fixed output voltages of 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V that have no minimum load requirement to maintain regulation.

Also included is an adjustable output version that can be programmed from 1.25 V to 20 V with two external resistors. On chip trimming adjusts the reference/output voltage to within ±2.0% accuracy. Internal protection features consist of output current limiting, safe operating area compensation, and thermal shutdown. The 矽源特MET1117 series can operate with up to 20 V input. Devices are available in SOT223， TO252-2L .
