The LT1965IQ-2.5#PBF is a high-performance, low dropout linear regulator (LDO) from Linear Technology, which is now part of Analog Devices. This regulator offers optimal stability while delivering up to 1.1A of continuous output current with a dropout voltage of just 300mV at full load. Designed to provide precision, low noise, and high power supply rejection ratio (PSRR), it is an excellent choice for sensitive RF and analog circuitry.

Key Features:

• Output Voltage: Fixed at 2.5V, ensuring a stable and regulated supply for consistent performance.
• Low Dropout Voltage: 300mV dropout at full load enhances efficiency and enables operation from low input voltages.
• High Output Current: Capable of delivering 1.1A of output current to power a wide range of devices.
• Low Noise: With only 40µVRMS of output noise, it provides clean power essential for noise-sensitive applications.
• High PSRR: Excellent power supply rejection ratio of 66dB at 1kHz, minimizing the impact of supply noise on the output voltage.
• Adjustable Output: An external resistor divider can be used to set the output voltage from 1.2V to 20V for design flexibility.
• Thermal Protection: Internal thermal shutdown and current limit protection safeguard the device and the load.
• Stable with Low ESR Capacitors: Stable with ceramic, tantalum, or aluminum electrolytic capacitors, providing design versatility.
• Package: Housed in a 16-lead plastic DFN package, which is both space-saving and thermally efficient.
