FAN1587AD33X

3A可调式/固定式低压降线性稳压器 3A Adjustable/Fixed Low Dropout Linear Regulator

Description

The FAN1587A, FAN1587A-1.5, and FAN1587A-3.3 are low dropout three-terminal regulators with 3A output current capability. These devices have been optimized for low voltage applications including VTT bus termination, where transient response and minimum input voltage are critical. The FAN1587A is ideal for low voltage microprocessor applications requiring a regulated output from 1.5V to 3.6V with an input supply of 12V or less. The FAN1587A-1.5 offers fixed 1.5V with 3A current capability for GTL+ bus VTT termination. The FAN1587A-3.3 offers fixed 3.3V current capability for logic IC operation.
