DESCRIPTION
The TK637XXAB6 type, the TK637XXH type and the
TK637XXS type are CMOS LDO Regulator ICs. The IC
offers low quiescent current, and good transient
performance.
They are designed for portable applications with space
requirements, battery powered system and any electronic
equipment.
They do not require a noise-bypass capacitor.
They offer low dropout voltage.
The output voltage is internally fixed from 1.5V to 4.2V.
