Working Principle

The SP6205EM5-L-2-5 is a Linear Voltage Regulator and is based upon the basic principle of a voltage regulator. It works by controlling the output voltage, by comparing the output voltage to a reference voltage. This comparison is done by the comparator, which then adjusts the output voltage by adjusting the duty cycle of a PWM block.The device consists of an input, a PWM block, a pass unit, an internal reference voltage generator, an output voltage adjuster, an output voltage Trim section and a comparator. The input voltage is stepped down by the PWM block, the pass unit and a series of filters, to the level of the reference voltage generated by the TLIM3. The output voltage is then further adjusted by the output voltage adjuster and output voltage trim sections, using an external resistor divider. The comparison of the output voltage to the reference voltage is done by the comparator, which then adjusts the duty cycle of the PWM block to stabilize the output voltage.

Conclusion

The SP6205EM5-L-2-5 from ST Microelectronics is a Linear Voltage Regulator that is used for powering a wide range of devices and applications. It has a low power consumption and low output dropout voltage and is also very efficient in converting the input power to output. It works on the principle of comparison between the output voltage to reference voltage and adjusting the PWM duty cycle to stabilize the output voltage. It is a versatile device that can be used for powering a variety of applications, including phones, Wearables, medical and industrial equipment, and LEDs.
