STMicroelectronics LD57100
The LD57100 is a high accuracy voltage regulator, which provides 1 A of current. It is equipped with an NMOS pass transistor, whose gate is biased by a dedicated pin, thus allowing the ultra-low drop performance even at very low input voltages. It is available in Flip Chip6 (0.8x1.2 mm), maximizing the space saving.| Part No. | LD57100 |

DESCRIPTION
This device is stabilized with a small ceramic capacitor on the output. The ultra-low drop, low quiescent current and short-circuit protection make the LD57100 suitable for low power battery-operated applications. An enable logic control function puts the LD57100 in shutdown mode allowing a total current consumption lower than 0.1 µA.
