LT1963IS8-2.5: Low Noise, Fast Transient Response LDO Voltage Regulator

The LT1963IS8-2.5 is a high-performance low dropout linear regulator (LDO) from Linear Technology, designed to deliver a fixed output voltage of 2.5V with an output current up to 1.5A. This regulator is well-suited for applications requiring a low noise supply and fast transient response.

Key Features

• Low Noise Output: With an output noise as low as 40µVRMS over a 10Hz to 100kHz bandwidth, the LT1963IS8-2.5 is ideal for sensitive RF and precision analog circuits.
• Fast Transient Response: The device's superior transient response ensures output voltage stability under rapid load changes, making it suitable for high-speed digital circuitry.
• High Efficiency: A low dropout voltage of typically 340mV at full load improves efficiency and allows operation with minimal input-to-output differential.
• Stable with Low ESR Output Capacitors: The regulator is stable with ceramic capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) than tantalum capacitors.
• Thermal Protection and Current Limiting: Built-in thermal shutdown and current limiting protect the device and the load from adverse conditions.
• Adjustable Output: While the LT1963IS8-2.5 comes with a fixed 2.5V output, it is also available in an adjustable version that can be set from 1.21V to 20V with a single external resistor.

Applications

• High Efficiency Linear Regulators
