The electronic components UCB1400 is a stereo audio codec equipped with touch screen and power
management interfaces.
It integrates an AC ’97 Rev. 2.1 interface for communication
to an AC link host controller such as the Intel Xscale™ processor. The stereo audio
codec inputs connect directly to a microphone or line level sources such as a CD
player. The stereo audio codec outputs at line level and can drive a headphone
directly. The touch screen interface connects directly to a 4-wire resistive touch
screen. A built-in 10-bit analog-to-digital converter provides readout of touch screen
and power management parameters.
Ten general-purpose I/O pins provide
programmable inputs and/or outputs to the system.
Hqew.net provide you with the national electronic component UCB1400BE original spot information, price reference, free PDF download Datasheet material and other hot ic components lm358,lm317,ne555,lm324 and lm339.

Ic components LM317T security applications circuit
Ic components LM317T production with adjustable manostat, often because potentiometer contact undesirable make output voltage rises, burned load.
If you would like to add a transistor (shown below), under normal circumstances, the base of potential 0 T1 deadlines, the circuit T1 without influence; And when W1 contact undesirable, the base of potential rise T1, when to 0.7 V, electronic component LM317T T1 conduction, will adjust voltage is reduced, output voltage, and also reduce to load protect. If remove triode, disconnect W1 center, 3.8 V small DianZhu attachment, output voltage measurement immediately burned as 21V.
And with a T1, small DianZhu brightness decreases, and now only electronic components LM317T output voltage, thus effectively for the protection of 2V the load.
