DESCRIPTION
The TK716xx is a low dropout linear
regulator housed in a small SOT23-5 package, rated at 500 mW. The phase compensation in the IC has been optimized to allow the use of ceramic or tantalum output capacitors. The device is in the “on” state when the control pin is pulled to a logic high level. An internal
PNP pass
transistor is used to achieve a low dropout voltage of 90 mV (typ.) at 50 mA load current. This devi...
