The ISL75051SEH, ISL75051SRH are radiation hardened

Features

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.

• DLA SMD 5962-11212

• Output current up to 3.0A at T = +150°C

• Output accuracy ±1.5% over MIL temperature range

• Ultra low dropout:

- 65mV (typical) dropout at 1.0A

- 225mV (typical) dropout at 3.0A

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 1µA.

• SET mitigation with no added filtering/diodes

• Input supply range: 2.2V to 6.0V

• Fast load transient response

• Shutdown current of 1µA (typical)

• Output adjustable using external resistors

• PSRR 66dB (typical) at 1kHz

• Enable and PGood feature

These devices are optimized for fast transient response and

single event effects. This reduces the magnitude of 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 means of the decoupling

capacitor value used on the BYP pin.

• Programmable soft-start/inrush current limiting

• Over-temperature shutdown and programmable OCP limits

• Stable with 47µF min tantalum capacitor

• Radiation environment

- High dose rate (50-300rad(Si)/s) . . . . . . . . . . 100krad(Si)

- Low dose rate (0.01rad(Si)/s) . . . . . . . . . . . . 100krad(Si)*

Applications

*Product capability established by initial characterization. The

“EH” version is acceptance tested on a wafer-by-wafer basis to

50krad(Si) at low dose rate.

• LDO regulator for space application

• DSP, FPGA, and µP core power supplies

• Post-regulation of switched mode power supplies

• Down-hole drilling
