SSP78MXX
SSP78MXX is three-terminal positive regulators. One of these regulators can deliver up to 500mA of output current. The internal limiting and thermal shutdown features of the regulator make them essentially immune to overload. When used as a replacement for a zener diode-resist or Combination, an effective improvement in output impedance can be obtained,together with lower quiescent current.
SSP1117
SSP1117 is a series of low dropout three-terminal regulators with a dropout of 1.3V at 1A load current. SSP1117 features a very low standby current 2mA compared to 5mA of competitor.Other than a fixed version, Vout=1.2V, 1.5V, 1.8V, 2.5V, 2.85V, 3.3V and 5V, SSP1117 has an adjustable version, which can provide an output voltage from 1.25 to 12V with only two external resistors.
SSP1117 offers thermal shut down function, to assure the stability of chip and power system. And it uses trimming technique to guarantee output voltage accuracy within 2%. Other output voltage accuracy can be customized on demand, such as 1%.SSP1117 is available in SOT-223, TO-252 power package.
SSP1922
SSP1922 is a high accurate time measurement (TDC) circuit. SSP1922 integrates analog comparator, analog switch, Schmidt flip-flop and other internal devices, thus greatly simplifying the peripheral circuit. At the same time, the first wave detection function is added inside, so that the anti-interference ability is greatly improved. The programmable offset range of the comparator is increased to ±35mV, the sampling accuracy can be improved.Measuring the relative pulse width of the first wave gives the user an indication of the strength of the received signal. Through this hint, we can judge the abnormal detection of ultrasonic transducer, the increase of wall covering, the presence of bubbles in water and so on. The Start-TOF-Restart command can complete a measurement of ultrasonic time difference (upstream and downstream) and data reading, so as to greatly reduce the software operation and power consumption. Compatible with TDC – GP22.
