data sheet g15368ej1v0ds 13 pc29m33a, pc29m05a notes on use when the pc29m33a, pc29m05a are used with an input voltage that is lower than the value indicated in the recommended operating conditions, a large quiescent current flows through the device due to saturation of the transistor of the output stage. (refer to the i bias (i bias(s) ) vs. v in curves in typical characteristics ). these products have saturation protector, but a current of up to 80 ma max. may flow through the device. thus the power supply on the input side must have sufficient capacity to allow this quiescent current to pass when the device starts up. reference documents document name document no. quality grade on nec semiconductor devices c11531e semiconductor device mounting technology manual c10535e voltage regulator of smd g11872e semiconductor selection guide ? products and packages x13769e
