Description

General part information

LD49100 Series

The LD49100 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 a wide range of automotive applications. Power supply rejection is 70 dB at low frequency and starts to roll off at 10 kHz. Enable logic control function puts the LD49100 in shutdown mode, allowing a total current consumption lower than 1 μA.

The device features a precise Power Good indicator, useful to monitor and sequence functions. Internal 1 ms soft-start circuit allows the reduction of inrush current.
