What are the key features of LT1964-5?
- 200 mA output current with only 300 mV dropout voltage at full load for efficient negative rail regulation
- Ultralow 30 µVRMS output noise making it ideal for precision analog, ADC, and RF bias supplies
- Micropower quiescent current of just 45 µA enabling battery-powered negative supply rails
What is LT1964-5 used for?
The LT1964-5 is designed for negative supply rail generation in battery-powered instruments, audio equipment, and precision ADC bias circuits requiring a clean -5 V rail. Its 30 µVRMS noise floor ensures minimal interference in high-resolution data acquisition and RF transceiver power supply networks. Medical devices, portable test equipment, and op-amp dual-supply circuits all benefit from its 200 mA current capability combined with micropower quiescent consumption.

Frequently Asked Questions
What is the output voltage and maximum current of the LT1964-5?
The LT1964-5 provides a fixed -5 V output voltage with a maximum load current of 200 mA. Its 300 mV dropout voltage at full load makes it efficient for negative rail applications where input and output rails are close together, minimizing power dissipation.
How does the LT1964-5's output noise compare to standard negative LDO regulators for RF bias supply design?
The LT1964-5 achieves only 30 µVRMS output noise from 10 Hz to 100 kHz, which is significantly lower than typical negative LDO regulators that may produce 80-200 µVRMS. This makes the LT1964-5 a strong choice for RF amplifier bias supplies, VCO circuits, and precision DAC references where noise floors below 50 µVRMS are required.
Can LT1964-5 power a negative rail in a portable instrument running from a single Li-Ion battery?
Yes, the LT1964-5 is suitable for portable instruments. Its 45 µA quiescent current extends battery life, and a charge pump can generate the negative input rail from a single Li-Ion cell. The SOT-23-5 package occupies minimal board area, and the -5 V fixed output supports op-amp dual-supply rails up to 200 mA output.
