In order to package the IC voltage regulator, a TO-263-5 case is used. On the Voltage regulator IC, there are 5 terminations that can be connected. At present, it can produce an output of up to 800mA. As you can see, the regulator IC has a total of 4 pins. Depending on the chip, 5 pins may be available. As far as the regulator type, it is a FIXED POSITIVE SINGLE OUTPUT LDO REGULATOR type. Generally, this voltage regulator IC can output 5V volts on a system level.
