DESCRIPTION/ORDERING INFORMATION

The LP2985 family of fixed-output, low-dropout regulators offers exceptional, cost-effective performance for both

portable and nonportable applications. Available in voltages of 1.8 V, 2.8 V, 2.9 V, 3 V, 3.3 V and 5 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 overcurrent and overtemperature protection, are

included.

The LP2985 has a host of features that makes the regulator an ideal candidate for a variety of portable

applications:

•

Low dropout: A PNP pass element allows a typical dropout of 280 mV at 150-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.

Low-ESR-capacitor friendly: The regulator is stable with low-ESR capacitors, allowing the use of small,

inexpensive, ceramic capacitors in cost-sensitive applications.

Low noise: A BYPASS pin allows for low-noise operation, with a typical output noise of 30 µV_RMS, with the

use of a 10-nF bypass capacitor.

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.
