LF33AB Datasheet (STMicroelectronics) - Very low drop voltage regulator

LF33AB, Very low drop voltage regulator

The LFXX is a very low drop regulator available in TO-220, TO-220FP, DPAK and PPAK packages and in a wide range of output voltages.

The low drop voltage (0.45 V) and low quiescent current make it particularly suitable for low-noise, low-power applications and especially in batterypowered systems.
