Description
TK111xxC is an integrated circuit of the silicon monolithic bipolar structure, and the regulator of
the low saturation output type with very little quiescent current(63A).
The PNP power transistor is built into. The I/O voltage difference when the current of Typ.200mA is
supplied to the system is 0.2V. The voltage source can be effectively used
Therefore, It is the best for the battery use set.
The on/off function is built into IC. The current at standing-by mode becomes slight (pA level).
1.5-10.0V is arranged to the output voltage in 0.1V step. The output voltage is trimmed in high
accuracy. The best voltage for the set used will be able to be selected.
The over current sensor circuit and the reverse-bias over current obstruction circuit are built into.
It is a design not broken because an ESD is also high. It is possible to use (*O) at ease.
When mounting on PCB, the loss becomes about 500mW though the package is very small.
TK111xxC uses the circuit with very high stability in DC and AC.
The capacitor on the output side is steady in 0.1F (1.8VVout). The kind of this capacitor is not
asked. It is possible to use every type capacitor.
However, a good characteristic is shown the more overall larger this capacitor is.
The ripple rejection is 84dB at 400Hz and 80dB at 1kHz.
