LD39100XX12 1 A low quiescent current low noise voltage regulator

The LD39100xx provides 1 A maximum current from an input voltage ranging from 1.5 V to 5.5 V with a typical dropout voltage of 200 mV. The device is stable due to the use of ceramic capacitors on the input and output. The ultra low drop-voltage, low quiescent current and low noise features make it suitable for low power battery powered applications. Power supply rejection is 65 dB at low frequencies and starts to roll off at 10 kHz. An enable logic control function puts the LD39100xx in shutdown mode, allowing a total current consumption lower than 1 μA. The device also includes short-circuit constant current limiting and thermal protection.
