The LDBL20 high accuracy voltage regulator provides 200 mA of maximum current from an input voltage ranging from 1.5 V to 5.5 V, with a typical dropout voltage of 200 mV.
It is available in the new STSTAMP™ package, allowing the maximum space saving.
The device is stabilized with a ceramic capacitor on the output. The ultra low drop voltage, low quiescent current and low noise features, together with the internal soft-start circuit, make the LDBL20 suitable for low power battery-operated applications.
An enable logic control function puts the LDBL20 in shutdown mode with a total current consumption lower than 0.2 µA. Constant current and thermal protection are provided.主な特徴
