ta58LT00F 2006-11-06 1 toshiba bipolar linear integrat ed ci rcuit silicon monolithic ta58LT00F 150 ma output current and tracking r egulator with on/off control switch the ta58LT00F consists of small-surface mount type tracking regulators with an output current of 150 ma (maximum) and an on/off control switch. control by an en (on/off) terminal enables the regulator to be operated only when required (output on). the output voltage can be controlled to an arbitrary voltage between 2.5v and 13.4v by applying a necessary voltage to adj through a microcontroller, etc. it is also possible to enable or disable the regulator via the enable (on/off) terminal. enabling the regulator only when necessary contributes to the energy saving of equipment. features ? built-in on/off control function (active high) ? maximum output current : 150ma ? output voltage : 2.5 v 13.4 v ? tracking voltage accuracy : 10mv (@t j = 25c) ? low standby current (output off mode) : 1 a (typ.) ? protection function : over-current protection / thermal shutdown / reverse connection of power supply / 60 v load dump ? package type : surface-mount new pw-mold5pin pin assignment marking hsip5-p-1.27b weight : 0.36 g (typ.) 58LT00F lot no. a line indicates lead (pb) - free package or lead (pb) - free finish. part no.
