Product Introduction
The LP2981 and LP2981A families of fixed-output, low-dropout regulators offer exceptional, costeffective performance for both portable and nonportable applications. Available in fixed voltages of 2.8 V, 3 V, 3.3 V, and 5 V, the family has an output tolerance of 0.75% for the A-grade devices (1.25% for the standard grade) and is capable of delivering 100 mA continuous load current. Standard regulator features, such as overcurrent and overtemperature protection, are included.
The LP2981 and LP2981A have features that make the regulators ideal candidates for a variety of portable applications:
Low dropout: A PNP pass element allows a typical dropout of 200 mV at 100 mA load current and 7 mV at 1-mA load. Low quiescent current: The use of a vertical PNP process allows for quiescent currents that are considerably lower than those associated with traditional lateral PNP regulators. Shutdown: A shutdown feature is available, allowing the regulator to consume only 0.01 μA when the ON/OFF pin is pulled low.
