The LP2966 is a dual ultra low-dropout regulator from ON Semiconductor that operates from a +2.70V to +7.0V input supply. The rated output current is 150mA, and the dropout voltage is extremely low, making it very suitable for battery powered and portable applications. The LP2966 features independent shutdown capability for each LDO and low noise performance with low ground pin current in an extremely small 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, many more are available upon request with minimum orders. In all, 256 voltage combinations are possible.
The LP2966 dual ultra low‑dropout (LDO) regulator operates from a +2.70 V to +7.0 V input supply and delivers 150 mA per output over the full temperature range. Each LDO has independent shutdown capability and provides low‑noise performance with a very low ground‑pin current, making it suitable for battery‑powered and portable applications.
Key features include ultra‑low dropout voltage (0.9 mV at 1 mA, 135 mV at 150 mA), less than 1 pA quiescent current in shutdown, error‑flag outputs, and a wide range of preset output‑voltage combinations (up to 256). The device is offered in an MSOP‑8 surface‑mount package and works with low‑ESR ceramic capacitors.
