DESCRIPTION
The TK72100CS-G, TK721xxCS-G and TK722xxCS-G are
low dropout linear regulator ICs with on/off control, which can
supply 150mA load current.
TK72100CS-G, TK721xxCS-G, TK722xxCS-Gは、出力電流
150mAを安定に供給できるon/offコントロール付低飽和レギ
ュレータICです。TK721xxCS-GとTK722xxCS-Gの出力電圧
は内部固定で高精度にトリミングされ、TK721xxCSGは-2.0V
より-9.5V、TK722xxCS-Gは-2.0Vより-9.5Vの間で設定でき
ます。またTK72100CS-Gの出力電圧は外部抵抗により-3.0V
より-17.5Vの間で自由に設定できます。
The output voltage of the TK72100CS-G, adjustable by
external resistors, is available from -3.0 to -17.5V. Trimmed
with high accuracy, The output voltage of the TK721xxCS-G
is available from -2.0 to -9.5V and that of the TK722xxCS-G is
available from -2.0 to -9.5V.
