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 2.5 V, 2.6 V, 2.7 V, 2.8 V, 2.85 V, 3 V,  
3.1 V, 3.2 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 over-current  
and over-temperature 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.  
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.
