LP2985-33 具有关断状态和 1.5% 容限的 150mA 低噪声低压降稳压器
LP2985-33 描述
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.
