TK111xxCS
LDO REGULATOR WITH ON/OFF CONTROL
TK111xxCS
1. 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 (63mA).
The PNP power transistor is Built-in to. 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-in to IC. The current at
standing-by mode becomes slight (pA level).
1.5 to 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-in to.
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 0.1mF
(1.8V£Vout). 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.
