KF33B Datasheet (STMicroelectronics) - Very low drop voltage regulators

KF33B, Very low drop voltage regulators

The KFxx series are very low drop regulators available in SO-8 package and in a wide range of output voltages.

The very low drop voltage (0.4 V) and the very low quiescent current make them particularly suitable for low noise, low power applications and specially in battery powered systems.
