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, 2.5 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:
鈥?/div>
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.
鈥?/div>
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.
鈥?/div>
Shutdown: A shutdown feature is available, allowing the regulator to consume only 0.01
碌A
when the
ON/OFF pin is pulled low.
鈥?/div>
Low-ESR-capacitor friendly: The regulator is stable with low-ESR capacitors, allowing the use of small,
inexpensive, ceramic capacitors in cost-sensitive applications.
鈥?/div>
Low noise: A BYPASS pin allows for low-noise operation, with a typical output noise of 30
碌V
RMS
, with the
use of a 10-nF bypass capacitor.
鈥?/div>
Small packaging: For the most space-constrained needs, the regulator is available in the SOT-23 package.
