The XL6009 is a Buck-Boost switching Regulator, meaning it takes in an Input Voltage and then switches it to produce a regulated output voltage which could be greater or lesser than the Input Voltage.
650V SiC Schottky Diodes with Current Ratings from 6A to 40A
The LM337 is a Variable Negative Voltage Regulator that can output voltage from -1.25V to -37V with a maximum output current of -1.5A.

The NTE960 is a 5V Voltage regulator IC with a maximum output current of upto 1A. It requires no external components and has in-built short-circuit and thermal overload protection.
The TL431 is a regulator diode whose output voltage can be programmed by changing the value of resistors connected to it. It acts almost like a Zener diode except for that the voltage rating of this IC is programmable.
The HLK-PM01 is a small size low cost AC to DC converter which can take in 110V/220V AC at 50/60 Hz and give 5V 3W output. The module is can be used in designs which run on 5V and needs to be powered form the AC mains.
