DESCRIPTION
The TK112xxB is a low dropout linear
regulator with a builtin 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.
An external capacitor can be connected to the noise bypass pin to lower the output noise level to 30 µVrms.
An internal
PNP pass
transistor is used to achieve a lo...
