STMICROELECTRONICS LD1085V LDO Regulator 1.8V/2.5V/3.3V/5V, 3A, TO-220
Low-dropout regulator with 3A output, fixed or adjustable voltage. Ideal for power management & industrial applications.
The STMICROELECTRONICS LD1085V is a high-performance low-dropout voltage regulator, capable of delivering up to 3A of output current. Designed for power management and industrial applications, it ensures a stable and regulated output with a tight tolerance of ±1% at 25°C.
This regulator features a guaranteed maximum dropout of 1.2V at full load, decreasing at lower currents, making it ideal for applications where a low voltage drop is critical. The LD1085 is pin-to-pin compatible with standard 3-terminal adjustable regulators but offers superior dropout and output tolerance. Its quiescent current flows into the load, enhancing overall efficiency compared to PNP regulators.
Key Features:
- Output current capability: 3A
- Input voltage range: 4.25V to 30V
- Output voltage options: fixed 1.8V, 2.5V, 3.3V, 5V, or adjustable from 1.25V to 4.25V
- Dropout voltage: 1.3V typical
- On-chip trimming for tight output tolerance
- Internal power and thermal limiting
- Requires only 10µF minimum capacitor for stability
- Through-hole TO-220-3 package
The LD1085 is an excellent choice for a wide range of power management tasks, providing reliable performance in industrial environments. Its ability to work with a low dropout and high efficiency makes it a practical solution for various voltage regulation needs.
