STMicroelectronics LD1086DTTR: High-Performance Adjustable Linear Voltage Regulation
The STMicroelectronics LD1086DTTR represents a benchmark in adjustable linear voltage regulation technology, engineered to deliver precise power management solutions for demanding industrial and automotive applications. This DPAK-packaged regulator combines robust performance specifications with advanced protection features, making it an ideal choice for engineers seeking reliable voltage regulation in space-constrained designs.
Technical Excellence in Power Management
Operating as a positive adjustable regulator, the LD1086DTTR demonstrates exceptional versatility with its wide input voltage range (up to 30V) and output adjustability from 1.25V to 28.5V. The device maintains stable output under varying load conditions thanks to its 1.5V dropout voltage specification at full 1.5A output current capacity. This combination of high current capability and low dropout characteristics enables efficient power delivery in battery-powered systems and automotive environments where voltage fluctuations are common.
| Parameter | Specification |
|---|---|
| Max Input Voltage | 30V |
| Output Range | 1.25V - 28.5V |
| Output Current | 1.5A |
| Dropout Voltage | 1.5V @ 1.5A |
| Quiescent Current | 10mA |
Advanced Protection Architecture
Built-in safety mechanisms ensure long-term reliability in challenging operating conditions. The integrated over-temperature protection (OTP) and over-current protection (OCP) circuits safeguard against thermal runaway and electrical faults, while maintaining stable output regulation. These features make the LD1086DTTR particularly suitable for automotive power systems, industrial control equipment, and portable electronics requiring fail-safe operation.
Engineered for modern electronics manufacturing, the TO-252-3 (DPAK) surface-mount package combines thermal efficiency with space-saving design. The device's 88dB PSRR (Power Supply Rejection Ratio) at 120Hz ensures clean output voltage even when powering noise-sensitive analog circuits. Its -40°C to 125°C operating temperature range meets the demands of both industrial and automotive environments.
Design Flexibility and Application Scope
The LD1086DTTR's adjustable output configuration offers design engineers significant flexibility. By incorporating just two external resistors, designers can precisely set the desired output voltage level. This adaptability makes it suitable for diverse applications including:
- Automotive power systems
- Industrial automation equipment
- Portable medical devices
- Telecom infrastructure
- Test and measurement instruments
When compared to conventional fixed-voltage regulators, this adjustable solution provides superior design versatility while maintaining excellent line and load regulation performance. The device's low quiescent current (10mA) further enhances efficiency in battery-powered applications, extending operational life between charges.
