Wide input tolerance
It works through voltage spikes and cold-crank events
Low power consumption
Very low quiescent current extends battery life
描述
The LDQ44 is a high accuracy voltage regulator, which provides 400 mA of current.
It is available in a DFN 2x2 6L package, to maximize space saving.
The device is stabilized with a small ceramic capacitor on the output. The low drop, low quiescent current, and short-circuit protection make the LDQ44 suitable for low power battery-operated applications.
An enable logic control function puts the LDQ44 in shutdown mode allowing a total current consumption lower than 0.3 μA. Thermal protection is also included.
