DESCRIPTION
TK70403 is a low dropout, linear regulator with a built-in
electronic switch. A pin for a bypass capacitor is provided,
which connects to the internal circuitry to lower the overall
output noise level.
An internal PNP pass-transistor is used in order to achieve
low dropout voltage (typically 30 mV at 2 mA load current).
This makes it possible to maintain a stable output voltage
as the battery voltage decreases, extending the useful
battery life.
The TK70403 is available in a miniature SOT-26 surface
mount package.
