description/ordering information

The LP2985LV family of fixed-output, low-dropout regulators offers exceptional, cost-effective performance for

both portable and nonportable applications. Available in voltages of 1.25 V, 1.35 V, 1.5 V, 1.7 V, 1.8 V, and

2 V, the family has an output tolerance of 1% for the A version (1.5% for the non-A version), and is capable of

delivering 150-mA continuous load current. Standard regulator features, such as over-current and

over-temperature protection, are included.

The LP2985LV has a host of features that makes the regulator an ideal candidate for a variety of portable

applications:

considerably lower than those associated with traditional lateral PNP regulators.

ON/OFF pin is pulled low.

small, inexpensive ceramic capacitors in cost-sensitive applications.
