The LD59100 is a 1 A LDO regulator designed for use in various environments. Its N-MOS topology allows reduction of the Rdson of the pass-element, maintaining a very low-dropout voltage even with very low input power supply voltage.
The device features very high PSRR characteristics over a wide frequency band, rendering it suitable for use as a secondary regulator for noise-sensitive applications.
The enable function can be used to further decrease the overall current consumption in shutdown mode.
The LD59100 embeds protection features, such as current limit, thermal shutdown and reverse output current protection.主要特性
