General Description
The LD6991/A is an ultra low quiescent micropower linear regulator with voltage detector circuit. For regulator circuit, the precision of feedback reference voltage is within ??% and output current is up to 90mA. As well, it can be stable with 1uF output capacitor which reduces the board space and cost. For voltage detector circuit, the reset threshold voltage accuracy is within ??% and the reset time period is adjustable by an external capacitor.
LD6991/A is available in a space saving SC70-6 package.
