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 feature low dropout voltage, 104 mV

@ 300 mA for V

OUT1

, 150 mV @ 150 mA for V

OUT2

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

OUT1

and V

OUT2

. The

input to the RESET function is connected to the V

DET

pin.The SHDN2 pin is used to control the output of

OUT2

only. V

OUT1

will power-up and down with V

In the case of the TC1301B, the detect voltage input of

the RESET function is connected internally to V

OUT1

Both V

OUT1

and V

OUT2

have independent shutdown

capability.

Additional features include an overcurrent limit and

overtemperature protection that, when combined,

provide a robust design for all load fault conditions.
