Part Description
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.
