The STMicroelectronics Low input voltage 200 mA ultra low dropout linear regulator is a high accuracy voltage regulator which provides 0.2 A of current. It is available in CSP 0.65 x 0.65 mm² package, SOT23-5L, allowing the maximum space saving. The device is stabilized with a small ceramic capacitor on input and output. The ultra-low drop, low quiescent current and short-circuit current foldback make the LD56020 suitable for low power battery-operated applications.
An enable logic control function puts the LD56020 in shutdown mode allowing a total current consumption lower than 0.1 μA. Thermal protection is also included.
