1. First of all, it needs to be clear that the voltage specification can be judged by the letters and numbers marked on the chip.
2. The 1117 regulator chip usually marks the corner of the housing with letters and numbers, such as ADJ and 1.5, where ADJ means the output voltage is adjustable and 1.5 means the output voltage is 1.5V.
Therefore, the output voltage specification of the chip can be judged according to the marked letters and numbers.
3. It is worth extending that when using the 1117 voltage regulator chip, it is necessary to choose the appropriate output voltage specifications according to your own needs, and set the input voltage reasonably according to the specific circuit and load situation to ensure that the chip works normally and provides a stable power output.
The 1117 voltage regulator chip can see the number of volts through the voltmeter.
Because the main function of the 1117 voltage regulator chip is to provide stable voltage output through the voltage regulator circuit, the output voltage value of the chip can be read directly through the voltmeter, so as to understand its volts.
When using a voltmeter to test the 1117 voltage regulator chip, it is necessary to pay attention to the correctness and stability of the circuit connection during the test to avoid inaccurate test results.
At the same time, when designing the circuit, it is also necessary to pay attention to the rated voltage value and maximum working voltage of the 1117 regulator chip to ensure its normal operation and avoid damage.
AWSM1117 has a suffix after, generally expressed as - voltage value, -1.5 indicates 1.5V, -3.3 indicates 3.3V output, -5 indicates 5V output. No numerical suffix represents pressure regulation type.
