The LDQ40 is a high accuracy voltage regulator, which provides 250 mA of current. It is available in an SOT23 5L, 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 LDQ40 suitable for low-power battery-operated applications. An enable logic control function puts the LDQ40 in shutdown mode allowing a total current consumption lower than 0.3 µA. Thermal protection is also included.
