LP2966 - Dual 150mA Ultra Low Dropout Regulators

Overview
The LP2966 dual ultra-low dropout (LDO) regulators operate from a 2.70 V to +7.0 V input supply. Each output provides 150 mA over temperature. The IC operates with extremely low voltage drop and quiescent current, making it ideal for battery powered and portable applications. Each LDO in the LP2966 has independent shutdown capability. The LP2966 offers low noise performance in a very small low ground pin current MSOP-8 package (package dimensions and connection diagrams for more information on the MSOP-8 package). A wide range of preset voltage options are available for each output. In addition to the voltage combinations listed in the ordering information table, more and more are available upon request with minimum order. Combinations of all 256 voltages are possible.

Main technical indicators Differential pressure: linearly changing load current. Typically 0.9mV at 1mA load current and 135mV at 150mA load current. Ground Pin Current: Typically 300µA at 1mA load current (one shutdown pin and 340µA pulled low) at 100mA load current.
Shutdown Mode: Both shutdown pins are pulled low when quiescent current is less than 1µA.
When the corresponding error flag: open-drain output, becomes low output drops below 10% of rated value.
High Precision Output Voltage: Multiple output voltage options guarantee accuracy from 1.8V to 5.0V at ±1% at room temperature.
