LP2985A 150mA Low-Noise Low-Dropout Regulator With Shutdown | TI.com

LP2985A (ACTIVE) 150mA Low-Noise Low-Dropout Regulator With Shutdown

 

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.
