STMicroelectronics LD56020 Ultra-Low Noise LDOs


STMicroelectronics LD56020 Ultra-Low-Noise LDOs are high accuracy voltage regulators delivering a 0.2A current. The LD56020 is stabilized with a small ceramic capacitor on input and output. The LD56020 provides ultra-low drop, low quiescent current, and short-circuit current foldback, ideal for low-power battery-operated applications. The device is put in shutdown mode via an enable logic control function, allowing a total current consumption lower than 0.1µA.

The STM LD56020 Ultra-Low-Noise LDOs offer thermal protection and are housed in a space-saving CSP 0.65 x 0.65 mm² SOT23-5L package.
