摘要

本文介绍了一种可调300mA CMOS LDO，采用双金属0.5µm 16V CMOS技术。它采用低电流带隙，只需要1.5µa。它包括一个对称运放，配置为电压跟随器，具有内置的自适应偏置行为。该电路空载时功耗为10µA，满载时功耗小于40µA，参考电压为1.25V。300mA时的压降电压一般为200mV。输入电压范围2.3V ~ 7V。

300mA adjustable LDO with 10µA ground current

This paper presents an adjustable 300mA CMOS LDO built in a double-metal 0.5µm 16V CMOS technology. It uses a low-current bandgap which needs only 1.5µA. It includes a symmetrical op amp configured as voltage follower, having a built-in adaptive bias behavior. The circuit consumes 10µA without load, less than 40 µA at full load, and uses a 1.25V voltage reference. Dropout voltage at 300mA is typical 200mV. Input voltage range is 2.3V to 7V.
