WebJun 22, 2024 · No. The AMS1117 is speced to allow up to 1.5 A only in specific circumstances, such as VIN being only 1.5V above Vout (So 5 + 1.5 = 6.5V In) and with sufficient cooling. The AMS1117 is a linear regulator so it basically acts like a giant resistor, so at ideal 1.5V drop out at 1.5A it's still putting out 3 Watts of heat. WebFeb 24, 2012 · Linear Voltage Regulator. This type of voltage regulator performs as a voltage divider. It employs FET in Ohmic region. The steady output is sustained by varying the resistance of voltage regulator with respect to the load. Generally, these types of voltage regulator are of two types: Series voltage regulator. Shunt voltage regulator.
WebAug 13, 2024 · The normal running current may be 30 mA but, under fault, current will rise. Drop-out voltage from data sheet: - So, at a load current of 120 mA the drop-out voltage is about 0.16 volts and the minimum voltage needed to run the regulator is 5.16 volts hence, the voltage across the resistors will be around 6.9 volts at a current of 115 mA. WebHowever, for most regulators the quiescent current is extremely small compared to the load current, so it’s sufficient to assume that the output current is equal to the input …
