CMOS LDO REGULATOR IC
TK630xxB
1. DESCRIPTION
The TK630xxB is a CMOS LDO regulator in very small
FC-4 package.
The IC is designed for portable applications with space
requirements.
The IC does not require a noise-bypass capacitance.
The IC offers very low dropout voltage.
The output voltage is internally fixed from 1.5V to 4.2V
in 0.1V steps.

The maximum ratings are the absolute limitation values with the possibility of damaging the IC.
When the operation exceeds this standard, quality can not be guaranteed.
