Low noise positive CMOS LDO regulator IC
ローノイズ正出力CMOS½½和レギュレータIC
TK631xxB/H/S
DESCRIPTION
The TK631xxB, the TK631xxH and the TK631xxS are CMOS
LDO regulator ICs with on/off control. These ICs has very
low noise characteristics. Therefor, the Noise Bypass
Capacitor is NOT required.
The TK631xxB is packaged in a miniature 4-bump flip chip.
The TK631xxH is packaged in a small SON2017-6.
The TK631xxS is packaged in SOT23-5.
They are suitable for small portable equipment with high-
density mounting.
Featuring low dropout, its dropout voltage is extra low 80mV
(at I
OUT
=100mA, V
OUT
=3.0V, TK631xxB).
The output voltage is available from 1.5 to 4.2V in 0.1V steps

TK631xxSは小型パッケージSOT23-5です。
高密度実装を必要とする携帯機器に最適です。
入出力間電圧降下は80mV(TK631xxB)と極めて½くなってい
ます。また、½ノイズである為、ノイズパスキャパシタ不
要です。出力電圧は内部固定で、1.5~4.2Vを0.1Vステップ
の間で設定できます。
