LP2981-29DBVTG4 Description

For both portable and nonportable applications, the LP2981-29DBVTG4 fixed-output, the low-dropout regulator provides excellent performance at an affordable price. The family, which comes in fixed voltages of 2.8 V, 3 V, 3.3 V, and 5 V, can produce 100 mA of continuous load current and has an output tolerance of 0.75% for A-grade devices and 1.25% for standard grade. Overcurrent and overtemperature protection are two common aspects of regulators.
