The LMS1587IS-1.5 is a high-performance, low-dropout (LDO) voltage regulator designed and manufactured by Texas Instruments. This regulator is capable of delivering a continuous output current of up to 3A with an input voltage range from 4.75V to 7V. The device provides a fixed output voltage of 1.5V, making it an excellent choice for applications requiring a stable and precise low-voltage supply.

Key Features

• High Output Current: Capable of delivering up to 3A of continuous output current.
• Low Dropout Voltage: Maintains regulation with a minimal difference between the input and output voltages, enhancing efficiency and allowing operation with very low input-output differentials.
• Fast Transient Response: Designed to maintain stable output voltage despite rapid changes in load, which is crucial for high-performance digital circuits.
• Fixed Output Voltage: Provides a stable 1.5V output, which is a common voltage requirement for many digital ICs and microprocessors.
• Thermal Protection: Features built-in thermal shutdown to protect the device from overheating.
• Overcurrent Protection: Includes current limiting features to protect the circuit from excessive load conditions.
• Adjustable Output: Offers the flexibility to adjust the output voltage with external resistors for specific application requirements (for the adjustable version).

Applications

The LMS1587IS-1.5 is suitable for a wide range of applications, particularly where high current and low voltage are required. It is ideal for:

• Microprocessor and microcontroller power supplies
• Low-voltage logic supplies
• Memory and DSP power supplies
• Post-regulation for switching supplies
