DESCRIPTION
TK717xxS is a low dropout linear regulator with a built-in
electronic switch. The internal switch can be controlled by
TTL or CMOS logic levels. The device is in the ON state
when the control pin is pulled to a logic high level. In the OFF
state, the output impedance becomes very low, quickly
discharging the output capacitor. An external capacitor can
be connected to the noise bypass pin to lower the output
noise level to 30 ~ 50 V
RMS
. An internal PNP pass transistor
is included to achieve a low dropout voltage of 103 mV at
100 mA load current. The TK717xx has an exceptionally
low quiescent current of 72 A at no load and 0.8 mA with
a 50 mA load. The standby current is typically 100 pA. The
circuit features very good stability. The ripple rejection is 90
dB at 400 Hz and 80 dB at 1 kHz. Stable operation is
achieved with an output capacitor as low as 0.22 F; a
capacitor of any type may be used. (However, the larger the
output capacitor is, the better the overall characteristics will
be.)
The TK717xxS is available in a very small SOT23-5 surface
mount package.
