100mA, Ultra Low Quiescent Current CMOS LDO Regulator
REV: 03
General Description
The LD6969 is a micropower linear regulator, featuring ultra
low quiescent current. The precision of feedback reference
voltage is within ±2% and output current is up to 100mA. As
well, the LD6969 can be stable with a 1μF output capacitor,
which reduces the board space and cost. It is suitable for the
battery-powered portable equipment, especially for those
that require standby power.
Features
z Shutdown current <1μA
z Ultra-Low Quiescent Current:5μA
z Low Dropout: 350mV @50mA
z Thermal Shutdown and Current Limiting Protection
z Wide Operating Voltage Range
z Stable with 1μF Output Capacitor
z Output Voltage: 1.5V to 3.4V (step 0.1V)
The LD6911 is available in a space saving SOT23-5,
SC70-3, SC70-6 or DFN-6L package.
