SNVSA46B June 2014 – January 2018 LM46001
For highest efficiency of operation, it is recommended that the BIAS pin be connected directly to VOUT when VOUT ≥ 3.3 V. In this self-bias mode of operation, the difference between the input and output voltages of the internal LDO are reduced and therefore the total efficiency of the LM46001 is improved. These efficiency gains are more evident during light load operation. During this mode of operation, the LM46001 operates with a minimum quiescent current of 24 µA (typical). See VCC, UVLO, and BIAS for more details.
