ISL72991RH

FN9054.1

Radiation Hardened Negative Low

Dropout Adjustable Voltage Regulator

The radiation hardened ISL72991RH is a low dropout

adjustable negative regulator with an output voltage range of

-2.25V to -26V. The device features a 1A output current

capability, an adjustable current limit pin (ILIM) and a

shutdown pin (SD) for easy on/off control.

The device incorporates unique circuitry that enables

precision performance over the -55°C to +125°C temperature

range and post-irradiation. Specifications include a reference

voltage of -1.25V +40mV/-50mV (max), line regulation of

±25mV (max), and load regulation of ±15mV (max).

Constructed with the Intersil dielectrically isolated Rad Hard

Silicon Gate (RSG) BiCMOS process, these devices are

immune to Single Event Latch-up and have been specifically

designed to provide highly reliable performance in harsh

radiation environments.

Specifications for Rad Hard QML devices are controlled

by the Defense Supply Center in Columbus (DSCC). The

SMD numbers listed here must be used when ordering.

Detailed Electrical Specifications for these devices are

contained in SMD 5962-02503. A ‘hotlink’ is provided on

the Intersil website for downloading.
