TK705xxS/TK706xxH

LDO Regulator IC

1-. DESCRIPTION

TK705xxS and TK706xxH 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.
