LD57100 Datasheet (STMicroelectronics) - 1A ultra low-dropout LDO

LD57100, 1A ultra low-dropout LDO

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
