Radiation Hardened Negative Low

Dropout Adjustable Voltage Regulator

Features

• Electrically Screened to DSCC SMD # 5962-02503

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

• QML Qualiﬁed per MIL-PRF-38535 Requirements

• Radiation Environment

- Total Dose (Max). . . . . . . . . . . . . . . . . . . . . 300krad(SI)

- Latch-Up Immune

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

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

LIM

• Line Regulation . . . . . . . . . . . . . . . . . . . . . +/-25mV (max)

The device incorporates unique circuitry that enables

precision performance over the -55C to +125C 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).

• Load Regulation . . . . . . . . . .+/-12mV (typ); +/-15mV (max)

• Output Voltage Range . . . . . . . . . . . . . . . . -2.25V to -26V

• Dropout Voltage (100mA). . . . . . . . 0.2V (typ); 0.3V (max)

• Dropout Voltage (1A) . . . . . . . . . . . . . . . . . . . . . 1V (max)

• Minimum Load Current. . . . . . . . . . . . . . . . . . . . . . .3.0mA

• TTL Input-Level Shutdown (SD); Low = On

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.

Applications

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.

• Switching Power Supplies

• DC/DC Converters

• Motor Controllers

Detailed Electrical Speciﬁcations for these devices are

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

the Intersil website for downloading.
