Description
The TC1301A/B combines two Low Dropout (LDO)
regulators and a microcontroller RESET function into a
single 8-pin MSOP or DFN package. Both regulator
outputs
@ 300 mA for V
low quiescent current consumption, 58 µA each and a
typical regulation accuracy of 0.5%. Several fixed-
output voltage and detector voltage combinations are
available. A reference bypass pin is available to further
reduce output noise and improve the power supply
rejection ratio of both LDOs.
The TC1301A/B is stable over all line and load
conditions with a minimum of 1 µF of ceramic output
capacitance, and utilizes a unique compensation
scheme to provide fast dynamic response to sudden
line voltage and load current changes.
For the TC1301A, the microcontroller RESET function
operates independently of both V
input to the RESET function is connected to the V
pin.The SHDN2 pin is used to control the output of

In the case of the TC1301B, the detect voltage input of
the RESET function is connected internally to V

capability.
Additional features include an overcurrent limit and
overtemperature protection that, when combined,
provide a robust design for all load fault conditions.
