Key Features
- Fixed 6 V regulated output with 0.06% maximum line regulation, ensuring stable supply for sensitive analog and RF circuits
- Wide input voltage range of 8.6 V to 19 V with 35 V absolute maximum, tolerating input transients common in automotive and industrial systems
- TO-39 metal-can package (R-PSFM-T3) providing superior thermal dissipation and mechanical robustness compared to plastic equivalents
- 2 V typical dropout voltage enabling use in 8 V to 6 V regulation scenarios where low headroom is critical
Applications
The L7806ABV is suited for benchtop instruments, RF transceiver boards, and industrial control panels that require a stable 6 V rail derived from an unregulated or battery-backed 9 V to 18 V supply. Its metal TO-39 package makes it a preferred choice for legacy military and telecommunications equipment where plastic-packaged regulators are disqualified by vibration or humidity specifications. It also serves as a pre-regulator stage ahead of lower-voltage linear regulators in multi-rail power supply designs.

Frequently Asked Questions
What is the fixed output voltage and acceptable input range for the L7806ABV?
The L7806ABV provides a fixed 6 V regulated output. It requires an input voltage between 8.6 V and 19 V for regulation, with an absolute maximum input rating of 35 V to protect the device during transients. The 2 V typical dropout means at least 8 V of input is needed to maintain the 6 V output under full load.
How does the L7806ABV's TO-39 metal-can package benefit designs in harsh environments compared to plastic-packaged regulators?
The TO-39 metal-can package offers a hermetically sealed or near-hermetic construction with a metal lid that resists moisture ingress and mechanical shock better than standard plastic DPAK or TO-220 packages. This makes the L7806ABV preferred in military avionics, telecom shelters, and outdoor industrial enclosures where humidity, vibration, and temperature cycling can degrade plastic-packaged devices over time.
What line regulation specification does the L7806ABV guarantee, and why does that matter for analog circuits?
The L7806ABV guarantees a maximum line regulation of 0.06%, meaning the output voltage shifts no more than 3.6 mV for a full input voltage sweep from 8.6 V to 19 V. For analog signal-conditioning circuits, op-amp reference stages, and ADC voltage references powered from 6 V, this tight regulation prevents supply-induced offset and gain errors in the measurement chain.
In which legacy or high-reliability applications is the L7806ABV still widely specified instead of modern switching regulators?
The L7806ABV remains specified in military-grade power supplies, vintage telecom line cards, and RF amplifier bias circuits where switching regulator ripple and EMI are unacceptable. At output currents below 500 mA, its low noise and zero switching frequency make it superior to a buck converter for powering low-noise amplifier bias rails at 6 V.
What thermal derating should a PCB designer apply when operating the L7806ABV at elevated ambient temperatures?
The L7806ABV in TO-39 has a thermal resistance junction-to-case of approximately 5°C/W. With a maximum junction temperature of 150°C, a designer must limit power dissipation (VIN − 6 V) × IOUT so that junction temperature stays below 150°C. At 25°C ambient with no heatsink, the device can safely dissipate roughly 1 W to 2 W depending on airflow, limiting output current at high input voltages.
