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. 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 10µA.

These devices are optimized for fast transient response and

Single Event Effects (SEE). This reduces the magnitude of

Single Event Transients (SET) seen on the output.

Additional protection diodes and filters are not needed.

These devices are stable with tantalum capacitors as low as

47µF and provide excellent regulation all the way from no

load to full load. Programmable soft-start allows the user

to program the inrush current by using the decoupling

capacitor value on the BYP pin.
