LP2981A-28 具有关断状态的 100mA 超低压降稳压器，0.75% 容差
LP2981A-28 描述
The LP2981 family of fixed-output, low-dropout regulators offers exceptional, cost-effective performance for both
portable and nonportable applications. Available in fixed voltages of 2.8 V, 3 V, 3.3 V, and 5 V, the family has an
output tolerance of 0.75% for the A-grade devices (1.25% for the standard grade) and is capable of delivering
100-mA continuous load current. Standard regulator features, such as overcurrent and overtemperature
protection, are included.
