Texas Instruments LP2985A-18 150mA Low-Noise Low-Dropout Regulators

Texas Instruments LP2985A-18 150mA Low-Noise
Low-Dropout Regulators

Texas Instruments LP2985A-18 150mA Low-Noise Low-Dropout Regulators offer exceptional, cost-effective performance. TI LP2985A-18 1.8V LDOs have an output tolerance of 1% and are capable of producing 150mA continuous load current. These TI low-dropout regulators include standard regulator features such as overcurrent and overtemperature protection. TI LP2985A-18 LDOs also offer a host of features that make the devices ideal for a variety of portable applications: low dropout, low quiescent current, an available shutdown feature, low noise, and small packaging. These TI devices are also stable with low-ESR capacitors.
