1. DESCRIPTION
TK705xxS/TK707xxS and TK706xxH/TK708xxH is a
low dropout linear regulator with ON/OFF control, which
can supply 100mA load current.
The IC is an integrated circuit with a silicon monolithic
bipolar structure.
The output voltage, trimmed with high accuracy, is
available from 1.5 to 5.0V in 0.1V steps.
The packages are the small and thin SON2017-6, and
the extremely versatile SOT23-5. The IC is designed for
portable applications with space requirements, battery
powered system and any electronic equipment.
Two kinds of pin configuration can be selected for each
package.
The over current, over heat sensor and reverse bias over
current protection circuits are built-in.
ESD is also high, so it won’t break easily. It is possible
to use at ease.
