DESCRIPTION/ORDERING INFORMATION

The LP2981 family of fixed-output, low-dropout regulators offers exceptional, cost-effective 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 has features that make the regulator an ideal candidate 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.

Small packaging: For the most space-constrained needs, the regulator is available in the SOT-23 package.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
