Description
The TC1302A/B combines two Low Dropout (LDO)
regulators 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 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 TC1302A/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.
Additional features include an overcurrent limit and
overtemperature protection that combine to provide a
robust design for all load fault conditions.
