The LT1587CT#PBF is a high-current adjustable linear regulator from Linear Technology, capable of delivering up to 3A. It features an adjustable output voltage based on a 1.25V reference, allowing flexible configuration. With a dropout voltage of 1.3V at full load and a quiescent current of 10 mA, it is designed for high-performance applications requiring substantial current. The TO-220-3 package ensures excellent thermal dissipation for demanding environments.
- High 3A Output Current: Supports power-hungry loads like FPGAs, DSPs, and actuators.
- Adjustable Output Voltage: Flexible 1.25V reference allows custom voltage settings for diverse applications.
- Low Dropout for Efficiency: 1.3V dropout at 3A minimizes power loss in post-regulation scenarios.
- Robust Thermal Package: TO-220-3 package provides excellent heat dissipation for continuous high-current operation.
High-Current Adjustable Power Supplies
The LT1587CT#PBF's 3A output capability and adjustable 1.25V reference make it ideal for building bench power supplies or local high-current rails where precise voltage setting is required.
Post-Regulator for Switching Supplies
With a 1.3V dropout at 3A, it can be used as a low-noise post-regulator after a DC-DC converter, reducing ripple and providing a clean adjustable output for sensitive loads.
FPGA and DSP Core Supplies
Modern FPGAs and DSPs require low-voltage, high-current cores. This LDO can supply 3A at adjustable voltages (e.g., 1.8V, 2.5V) with low output noise.
Battery Charger Circuits
The adjustable output allows precise voltage control for charging lithium-ion or lead-acid batteries, with the high current capability supporting fast charging.
Audio Amplifier Rails
For high-fidelity audio amplifiers, the LT1587 provides a stable, low-noise adjustable supply, improving dynamic range and reducing hum.
