ISL75051ASEH, ISL73051ASEH
3A, Radiation Hardened, Positive, Ultra-Low Dropout Regulator
FN8964 Rev.3.00 May 16, 2019
The ISL75051ASEH and ISL73051ASEH are radiation hardened low-voltage, high-current, single-output LDOs specified for up to 3.0A of continuous output current. These devices operate across an input voltage range of 2.2V to 6.0V and can provide output voltages of 0.8V to 5.0V adjustable, based on the resistor divider setting. Dropout voltages as low as 65mV can be achieved using the device.
The OCP pin allows the short-circuit output current limit threshold to be programmed by a resistor from the OCP pin to GND. The OCP setting range is 0.5A minimum to 8.5A maximum. The resistor sets the constant current threshold for the output under fault conditions.
