Analog Devices Inc. LT1762/LT1962 Demo Boards DC339A-A/B

Analog Devices LT1762/LT1962 Demo Boards DC339A-A/B are demonstration and evaluation platforms for the LT1762 and LT1962 Low Noise Micropower LDO (Low Dropout) Regulators. The DC339A-A and DC339A-B each feature a typical application circuit and include a pre-mounted LT1762 or LT1962 in the 8-lead MSOP package. These evaluation boards have an input voltage range from 2.3V to 20.0V and a jumper-selectable output voltage that can be set to 1.22V, 2.5V, 3.0V, 3.3V, 5.0V, or a user-defined value. The low 20µVRMS (10Hz to 100kHz bandwidth) output noise and low 30µA quiescent current of the LT1762 and LT1962 make these devices ideal for voltage-controlled oscillators, RF power supplies, and local regulators in larger systems.
