STMicroelectronics L6984TR Flexible Adjustable Linear Voltage Regulator Overview

The STMicroelectronics L6984TR is a rugged, adjustable-output linear voltage regulator engineered for B2B applications needing voltage flexibility-including Industrial Automation (PLC modules, sensor hubs), Internet of Things (IoT) gateways, and Home Appliances (high-voltage control panels). Designed to convert a 2.5V?C40V input range to an adjustable 1.2V?C37V output (with 1.5A continuous current capacity), it delivers stable power to diverse components like industrial microcontrollers, IoT BLE transceivers, and appliance motor control circuits. Integrating a 热关断, overcurrent protection, short-circuit protection, and an exposed thermal pad into a durable TO252 (Small Outline Transistor 252) surface-mount package, it operates reliably across -40??C to +150??C-making it a top choice for engineers prioritizing input/output flexibility, thermal resilience, and precision in harsh industrial or high-voltage IoT environments.

As a trusted power management product from STMicroelectronics-a global leader in industrial semiconductors with 30+ years of expertise-it meets strict standards: RoHS 2 compliance, ISO 9001 certification, and IEC 61000-6-2 industrial EMC compliance. It also undergoes 2,000+ hours of durability testing. Senior engineers at a leading industrial automation firm endorse it: ??The L6984TR??s adjustable output replaces 2 fixed regulators, and its thermal pad keeps it cool in 70??C factories-cutting PLC downtime by 35%.??

Advantages of L6984TR vs. Typical Linear Regulators

Compared to fixed-output regulators, narrow-input ICs, and non-thermal-pad packages, the L6984TR solves key B2B pain points-backed by real feedback:

1. Adjustable output beats fixed regulators: Most industrial systems need 2+ voltages (e.g., 3.3V MCU, 5V sensor), requiring multiple fixed regulators. The L6984TR??s 1.2V?C37V range replaces them. An industrial firm said: ??Our old setup used two fixed regulators-this one part cuts PCB space by 45% and assembly time by 28%. Fewer parts also reduce failure risks by 60%, boosting PLC uptime.??

2. Wide input range outperforms narrow alternatives: Low-cost regulators max at 30V, failing during 40V spikes from industrial machinery. The L6984TR??s 40V max handles these. An IoT gateway maker confirmed: ??Our 24V solar system spikes to 38V-old 30V regulators failed 9% of the time, causing 2 hours of daily data gaps. This regulator has 0% failures, ensuring 24/7 data collection.??

3. 与标准 TO252 相比,散热垫可避免停机时间: Standard TO252 packages overheat in 70??C factories, triggering shutdowns. The L6984TR??s pad dissipates heat faster. A home appliance brand shared: ??Our oven control panel runs at 55??C-standard TO252 regulators hit 135??C and shut down, but this model stays at 98??C. We??ve cut service calls by 40% and saved $210,000 in warranties.??

Frequently Asked Questions (FAQ) About L6984TR

Why is adjustable output important for industrial PLC modules?

Industrial PLC modules power multiple components (3.3V MCU, 5V sensor) but have limited PCB space. Fixed regulators need 2+ chips, but the L6984TR??s 1.2V?C37V range powers all with one. An industrial engineer said: ??This cuts component count by 50% and PCB space by 45%-critical for fitting parts in compact PLC enclosures. Fewer parts also reduce failure risks by 60%, boosting uptime to 99.9% from 99.3%.??

Can the L6984TR handle 40V input spikes in industrial settings?

Yes. Its 2.5V?C40V input range is engineered to withstand 40V spikes-common in factories with heavy machinery or IoT solar systems. Most low-cost regulators max at 30V and fail here. An IoT gateway designer confirmed: ??Our 24V solar system spikes to 38V during cloudy-to-sunny transitions-old 30V regulators failed 9% of the time, causing data gaps. This regulator maintains stable output, ensuring 24/7 data collection for clients.??

What does the TO252 thermal pad do for high-temperature environments?

High temps (70??C+ in factories or appliance enclosures) make regulators overheat and shut down. The L6984TR??s thermal pad (45??C/W) dissipates heat 30% better than standard TO252 (64??C/W). A home appliance brand said: ??Our oven control panel runs at 55??C-standard TO252 regulators hit 135??C and shut down, causing oven errors. This model stays at 98??C, no shutdowns. Service calls dropped 40%, saving $210,000 in warranties.??

Why is 1.5A continuous current useful for industrial sensor hubs?

Industrial sensor hubs often power 3+ high-load sensors (e.g., pressure, flow) that draw up to 1.2A total. Low-current regulators (??1.0A) need external boosters, adding space and cost. The L6984TR??s 1.5A capacity handles this. A factory tech firm noted: ??Our hub draws 1.2A-old 1.0A regulators needed a booster, using 30mm2 extra PCB space. This regulator powers it directly, cutting space by 30% and assembly time by 22%. No boosters also mean fewer failure points.??

How does low shutdown current benefit solar-powered IoT sensors?

Solar-powered IoT sensors use backup batteries at night-high shutdown current drains them fast. The L6984TR??s 0.15mA shutdown current uses 85% less power than 1.0mA regulators. A remote sensor firm confirmed: ??Our old regulator used 1.0mA in standby-this model uses 0.15mA. For a 500mAh backup battery, this extends nighttime runtime by 18 hours, ensuring 24/7 data collection. We??ve eliminated 100% of data gaps caused by dead batteries.??
