May 22, 2017 3A, Radiation Hardened, Positive, Ultra-Low Dropout Regulator
The ISL75051SEH, ISL75051SRH are radiation hardened
low-voltage, high-current, single-output LDOs specified for up
to 3.0A of continuous output current. These devices operate
over an input voltage range of 2.2V to 6.0V and are capable of
providing output voltages of 0.8V to 5.0V adjustable, based on
resistor divider setting. Dropout voltages as low as 65mV can
be realized using the device.
The OCP pin allows the short-circuit output current limit
threshold to be programmed by means of a resistor from the
OCP pin to GND. The OCP setting range is from 0.5A minimum
to 8.5A maximum. The resistor sets the constant current
threshold for the output under fault conditions. The thermal
shutdown disables the output if the device temperature
exceeds the specified value. It subsequently enters an ON/OFF
cycle until the fault is removed. The ENABLE feature allows the
part to be placed into a low current shutdown mode that
typically draws about 1ВµA.
These devices are optimized for fast transient response and
single event effects. This reduces the magnitude of SET seen …
