Products that require a feature-rich, low-power, and small form factor solution turn to the 51658-001LF. This low-profile capacitor-style voltage regulator offers a wide range of features, such as high efficiency, wide input voltage range (from 3.3V to 48V), low output ripple, output current up to 2A, short circuit protection, and over temperature protection.

The 51658-001LF regulator has a wide application field, spanning from industrial to consumer electronics. It becomes ideal for applications that require a robust power supply solution with fast transient response, high power density, and low thermal shutdown temperature. It can be easily configured to meet the specific power needs and form factor of the application. It offers excellent line and load regulation, and a maximum output current of 2A.

It working principle is quite simple and reliable. The 51658-001LF regulator uses a buck converter topology to step down the input voltage to its desired output voltage. The main components of s buck converter are: a voltage control circuit, an inductor, schottky diodes, and output capacitors. The voltage regulator is powered by an external DC voltage to power the regulator. The voltage regulation part of the voltage regulator is the most important part, as it converts the input voltage to the desired output voltage. The 51658-001LF voltage regulator computes the difference between the input voltage and the desired output voltage to determine how much current to allow through the inductor. The P-channel MOSFET is then pulsed to provide the regulated output voltage.

The output capacitor helps to smooth out the current pulses from the inductor to provide a more stable output voltage. The regulator is protected from short circuits and over temperatures by the included circuit current limit protection and temperature limit protection. The circuit can also be utilized to turn on and off power to external devices.

In conclusion, the 51658-001LF is a high-performance voltage regulator with multiple advantages and a wide application field. Its reliable and manageable working principle has made it the perfect choice for those applications where a robust, high efficiency, and low-power solution is required.
