LP2966
Description
The LP2966 dual ultra low-dropout (LDO) regulator operates from a +2.70V to +7.0V input supply. Each output delivers 150mA over full temperature range.
Key Features
- n n n n n n n n n
- Ultra low drop-out voltage Low ground pin current < 1µA quiescent current in shutdown mode Independent shutdown of each LDO regulator Output voltage accuracy ± 1% Guaranteed 150mA output current at each output Low output noise Error Flags indicate status of each output Available in MSOP-8 surface mount packages Low output capacitor requirements (1µF) Operates with Low ESR ceramic capacitors in most applications
- Over temperature/over current protection n -40˚C to +125˚C junction temperature range Key Specifications Dropout Voltage: Varies linearly with load current. Typically 0.9 mV at 1mA load current and 135mV at 150mA load current. Ground Pin Current: Typically 300µA at 1mA load current and 340µA at 100mA load current (with one shutdown pin pulled low). Shutdown Mode: Less than 1µA quiescent current when both shutdown pins are pulled low. Error Flag: Open drain output, goes low when the corresponding output drops 10% below nominal. Precision Output Voltage: Multiple output voltage options available ranging from 1.8V to 5.0V with a guaranteed accuracy of ± 1% at room temperature.
