Frequently Asked Questions
How can I program the adjustable output voltage?
The output voltages are available through innovative factory EEPROM programming, typically in 50mV increments (from 0.9V to 1.5V) or 100mV increments (from 1.5V to 3.6V).
What is the device's dropout voltage and maximum current?
The unit has an ultra-low dropout voltage of 115mV at a nominal load current of 3.0A (typ).
Is this regulator suitable for critical applications like military use?
No; it is only intended for standard non-critical uses. TI products are neither designed nor intended for use in military/aerospace environments unless specifically designated as such.
What special care should be taken when handling the integrated circuit?
Since it can be damaged by Electrostatic Discharge (ESD), Texas Instruments recommends that all integrated circuits be handled with appropriate precautions.
