LA5160AM no.8319-4/6 specified test circuit diagram cautions for application note : 1) to stabilize the operation, arrange cin and cout as near as possible to the ic. 2) cout must have 0.1 f or more, with less capacitance fluctuation due to temperature, so as to prevent oscillation at low temperature (such as a tantalum capacitor, etc.). 3) with the stb pin open, the internal bias causes the output in the on state. when the stb function is not to be used, connect the stb pin to gnd to ensure trouble-free operation of stb. 4) note that wrong connection, such as connection of v in to minus and gnd to plus, may cause flow of the overcurrent. function table equivalent circuit for on/o ff control input, etc. vstb v out l h h l LA5160AM stb 2 3 7 5 cout=0.1 f v out cin=0.33 f v in nc 1 nc 4 gnd 6 8 nc nc t t 0 0 vstb v out stb 5 300 ? 50k ? 50k ? 50k ?
