- 1A output current capability in a compact 3-pin DPAK surface-mount package
- Wide input voltage range of 8.5V to 21V (absolute maximum 35V) for versatile application
- 2V nominal dropout voltage providing efficient headroom utilization from available supply rails
- RoHS compliant single-channel linear regulator for consumer and industrial power designs
What is BA7806FP-E2 used for?
The BA7806FP-E2 fixed 6V linear voltage regulator is ideal for post-regulation stages in consumer electronics, set-top boxes, and industrial control boards where a stable 6V rail is needed from a higher-voltage DC supply. Its 1A current rating and DPAK package with exposed heatsink paddle enable efficient thermal management in medium-power applications such as motor pre-driver bias supplies and LED driver power rails. The device also serves as a local voltage regulator in automotive accessory circuits and industrial sensor power supplies operating from 12V or 24V bus voltages.

Frequently Asked Questions
What is the output voltage and current rating of the BA7806FP-E2, and how accurate is the output regulation?
The BA7806FP-E2 delivers a fixed 6V output with ±4% accuracy at up to 1A continuous output current. Its line regulation and load regulation are both specified at a maximum of 0.12%, ensuring the 6V rail remains stable across varying input voltages from 8.5V to 21V and load currents from near-zero to the full 1A rated output, making it suitable for precision analog and mixed-signal power supplies.
How does the DPAK package of the BA7806FP-E2 help manage heat dissipation in a 1A linear regulator application?
The DPAK (TO-252) package includes an exposed metal heatsink tab on the bottom of the package that can be soldered directly to a PCB copper pour, providing a low thermal resistance path to dissipate the power lost across the regulator. At 1A load with a 12V input and 6V output, the device dissipates approximately 6W, so proper PCB copper area sizing is critical to keep junction temperature below the maximum rated limit and ensure reliable long-term operation.
Can the BA7806FP-E2 regulate a 6V output from a 12V automotive supply, and what input voltage margins apply?
Yes, the BA7806FP-E2 operates from an input voltage range of 8.5V minimum to 21V maximum, making it directly compatible with nominal 12V automotive supply rails which can range from approximately 9V during cold cranking to 14.4V during alternator charging. The 2V dropout voltage means the device requires at least 8V input to maintain a regulated 6V output, providing sufficient margin across the full automotive voltage specification window.
What distinguishes the BA7806FP-E2 from adjustable linear regulators for fixed 6V power rail designs?
Unlike adjustable regulators such as the LM317 that require 2 external resistors to set the output voltage, the BA7806FP-E2 provides a factory-trimmed fixed 6V output requiring no external resistor divider, reducing component count and eliminating output voltage setting errors caused by resistor tolerance variations. This simplifies PCB design and reduces BOM cost for production designs that always require exactly 6V regulation from a single input supply.
