STMicroelectronics LD59100
The LD59100 is a 1 A LDO regulator designed for use in various environments. Its NMOS 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.| Part No. | LD59100 |
