Este módulo es ideal para regular la tensión de la batería de 6 V, 9 V o 12 V hasta el nivel de 5.0 V requerido por muchos circuitos electrónicos.
Especificaciones:
Entrada: 6 V a 12 V CC en + y - terminales.
Salida: 5,0 V a 1000 mA de corriente máxima en los terminales de salida. La corriente máxima está limitada por la disipación de potencia interna del regulador y no puede proporcionar salida de 1000 mA a todos los voltajes de entrada. **
Dimensiones: 25 x 10 x 3 mm.
Los pines para los conectores de entrada y salida están soldados en la placa para una fácil conexión. Un LED montado en PCB se ilumina cuando se aplica voltaje al módulo.
** El regulador de voltaje AMS1117 utilizado en este módulo es un regulador de voltaje lineal, y puede ponerse muy caliente al disipar corrientes más altas con caídas de voltaje más grandes. La corriente de salida máxima real está limitada por la capacidad de disipación de energía interna del dispositivo, y no puede proporcionar corriente de salida de 1000 mA en todos los niveles de entrada de voltaje.
El paquete incluye:
10 x 6 V – 12 V en 5,0 V salida AMS1117-5 Step-Down Linear regulador de voltaje Power Converter Module

I'm no novice when it comes to electronics. I've had a long career as an EE and linear regulators are as simple as it gets. In fact, I often choose the less-efficient linear devices over buck converters due to their simplicity and reliability. They also do not induce noise as the active buck converters do. Not these, though. . . failing left and right. The ones that aren't dead on arrival, work for a while then the output swings high and starts tracking input never to regulate to 5V, again.These devices are failing on low-current loads (max. 50mA) when they are rated at 1000mA when not dropping much voltage. (Linear regulators are more efficient when the input is close to the output since the power is a function of voltage and current. The more voltage dropped by the regulator, the more likely it is to get too hot and die the thermal death.) Not sure how they can rate the device at 1000mA and 12V input when that is a power drop of 7W! Clearly not going to happen with an SMD regulator. But, that is not my issue, just a warning to others.so, never mind that. . . 30% of these were failed on arrival and the are not failing open, they are failing by sending the input voltage to the output. Say bye-bye to your circuit! The output is not the full input voltage, but it does track the input voltage. When 11V is applied, a full 9.3V is sent to the load. Not good.And why are they failing? It doesn't get much easier than a linear monolithic device. I should have just built my own, but these were priced right and came with header pins.Save yourselves some headaches (now or down the road) and buy something more reliable even if it doesn't have the low voltage differential (input to output) this device has.

Works as advertised, perfect for small-system application. I used it to power a bluetooth module from my car battery, and it works FLAWLESSLY

Does exactly what it says. My voltmeter reads 4.99V when powered with 9V battery.
