            LDQ40 LDO Linear Regulators
                    STMicroelectronics' high-accuracy voltage regulator provides 250 mA of current
    

Image of STMicroelectronics LDQ40 LDO Linear Regulators STMicroelectronics' LDQ40 is a high-accuracy voltage regulator that provides 250 mA of current. It is available in SOT23 5L, DFN2x2 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.
