Application examples:
1) Adjustable three terminal regulator module can replace 7805,7806,7809,7812,7824 and all three off regulator module
2) vehicle-mounted power supply, only need to enter this module termination point the car cigarette power supply, you can adjust the potentiometer, the output voltage can be adjusted to allow you your cell phone, MP3 at 1.25V-30V, MP4, many devices powered PSP charging, very easy oh.
3) In order to power your electronic devices when your device needs power when 1.25-60V, but your hands now only 12V or 24V battery, this module can directly use our buck 1.25-30V, solve your problems .
4). Preamp power supply system, when you do a project when you need to input supply voltage drops below a voltage (1.25V-30V) when the module will be your best choice.
