The Enable pin (active-high) pulls the output to zero when driven low, drawing 9 mA quiescent in the enabled state. Sequencing multiple rails is a matter of tying the enable to a GPIO or a supervisor output — no external PMOS load switch needed. ROHS3 compliance covers EU and global regulatory requirements without exemption paperwork.","metaTitle":"Texas Instruments LP3962ET-3.3/LB05 LDO Regulator","metaDescription":"Texas Instruments LP3962ET-3.3/LB05 fixed 3.3V LDO, 1.5A output, 0.55V dropout at full load, TO-220-5, -40 to 125°C.
