What are the key features of LT3015EDD-5#PBF?
- Fixed -5 V negative output LDO providing 1.5 A with 0.31 V typical dropout, enabling efficient negative rail regulation down to 5.81 V input
- Precision internal current limit protects the load and downstream circuitry from fault conditions without external sense resistors
- 8-lead DFN (S-PDSO-N8) package with low-noise design suits analog signal chains requiring a clean negative supply rail
What is LT3015EDD-5#PBF used for?
LT3015EDD-5#PBF is ideal for powering operational amplifiers, instrumentation amplifiers, and analog front ends that require a stable negative -5 V rail from a higher negative input supply. Its 1.5 A current capability and low 0.31 V dropout make it suitable for precision data acquisition systems, audio equipment, and industrial sensor conditioning circuits. The precision current limit feature also makes it a robust choice for protecting sensitive analog circuitry in test-and-measurement equipment.

Frequently Asked Questions
What output voltage and current does LT3015EDD-5#PBF provide, and what is its dropout voltage?
LT3015EDD-5#PBF delivers a fixed -5 V output at up to 1.5 A with a typical dropout voltage of 0.31 V and a maximum of 0.5 V. This means the device can regulate -5 V with an input as low as -5.5 V. The combination of high current and low dropout makes it efficient for powering op-amp negative rails and precision analog circuits.
What input voltage range does LT3015EDD-5#PBF support, and how does it handle transient overloads?
LT3015EDD-5#PBF accepts input voltages from -5.5 V to -30 V, giving designers wide headroom for unregulated negative supplies. The internal precision current limit activates automatically during overloads and short-circuit events, clamping output current to the programmed limit without requiring external sense resistors. This protects both the regulator and downstream analog components without adding board complexity.
Which board-level applications benefit from using LT3015EDD-5#PBF as a negative supply post-regulator?
Instrumentation amplifiers, ADC/DAC bias rails, and precision op-amp circuits operating on split ±5 V supplies benefit most from LT3015EDD-5#PBF as a post-regulator. At 1.5 A capacity with 0.31 V dropout and a low-noise design, it cleans switching-converter ripple on the negative rail below the noise floor of 16-bit and 24-bit converters. Industrial sensor conditioning boards, audio DACs, and medical signal front ends are typical deployment environments.
How compact is the LT3015EDD-5#PBF package, and does it require an external heatsink at full load?
LT3015EDD-5#PBF occupies an 8-lead DFN (S-PDSO-N8) footprint measuring approximately 3 mm x 3 mm. At full 1.5 A load with a 10 V input-output differential, the device dissipates up to 15 W; the exposed pad transfers heat to the PCB copper pour, which typically suffices for dissipation up to 1 W to 2 W without an external heatsink. For higher dissipation, a 2-oz copper ground plane or external heatsink pad is recommended.
