LDQ40 250mA Low-Dropout (LDO) Voltage Regulator

STMicroelectronics LDQ40 250mA Low-Dropout (LDO) Voltage Regulator is a high-accuracy voltage regulator that provides 250mA of current. It is available in a 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.
