Working Principle

The L88MS05TL-TL-E is a low-dropout/low-noise linear voltage regulator module. Ultrasmall Type L88MS (or S88MS) chips, which are onboard the L88MS05TL-TL-E, control the regulator’s internal MOSFET, which acts as the primary pass element for current regulation. The voltage reference of the regulator is set with an external number-of-turns potentiometer, along with a resistor network.

The output voltage of the regulator is set by an external voltage reference that is compared with the output voltage using an internal error amplifier. The input voltage is applied to the gate of the pass MOSFET to adjust its ON resistance. The gate voltage is then regulated by the error amplifier to reach the desired output voltage. A feedback network senses the output voltage and compares it to the reference voltage. The difference between the reference voltage and the output voltage is then amplified and used to control the gate voltage of the MOSFET.

The L88MS05TL-TL-E module also has some protection features, such as overcurrent protection and thermal shutdown. The overcurrent protection holds the MOSFET gate voltage to a regulated level in case of an overcurrent condition. The thermal shutdown circuit monitors the chip temperature and shuts off the power supply if the temperature exceeds its limit.

Conclusion

The L88MS05TL-TL-E is a low-cost linear voltage regulator module designed for applications requiring low-noise, low-voltage, high-current and high-efficiency regulation. It has a wide input voltage range and output voltage range, and features a low quiescent current and low dropout voltage, making it an ideal choice for many applications. Its protection features ensure reliable and safe operation of the device.
