Description
General part information
LD39100 Series
The LD39100 provides 1 A maximum current with an input voltage range from 1.5 V to 5.5 V and a typical dropout voltage of 200 mV. The device is stable with ceramic capacitors on the input and output.
The ultra-low dropout voltage, low quiescent current and low-noise features make it suitable for low power battery-powered applications. Power supply rejection is 70 dB at low frequency and starts to roll off at 10 kHz.
Enable logic control function puts the LD39100 in shutdown mode, allowing a total current consumption lower than 1 µA. The device also includes short-circuit constant current limiting and thermal protection.
