Io=150mA Iq=10μA キャパシタレスCMOS低飽和レギュレータIC  
TK637XXAB6  
TK637XXH  
(SON2017-6)  
TK637XXS  
(SOT23-5)  
(FC-4)  
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.  
TK637XXAB6タイプ、TK637XXHタイプ、TK637XXSタイプ  
は、CMOS低飽和レギュレータICです。低い電源電流であり  
ながら、良好な過渡特性を特長とします。  
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.  
高密度実装を要求される携帯機器、バッテリ使用機器や一般  
機器等に最適です。  
ノイズパス容量を必要としません。  
低い入出力間電圧降下を特長とします。  
出力電圧は内部固定で、1.5V ~ 4.2Vで設定可能です。  
The output voltage is internally fixed from 1.5V to 4.2V.
