3 Description
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, 3.1 V, 3.3 V, 5 V, and 10 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.
