Product Overview: LT1965IDD-1.8#TRPBF

The LT1965IDD-1.8#TRPBF is a high-performance low dropout linear regulator (LDO) from Analog Devices Inc., designed to deliver a continuous output current of up to 1.1A with an output voltage of 1.8V. This regulator offers excellent power supply rejection ratio (PSRR) and low noise characteristics, making it suitable for sensitive RF supply applications and post-regulation for switching power supplies.

Key Features

• Output Current: Capable of delivering up to 1.1A of continuous output current.
• Low Dropout Voltage: Features a low dropout voltage, ensuring efficient operation even when the input voltage is close to the output voltage.
• High PSRR: Excellent power supply rejection ratio (PSRR) of up to 65dB at 1kHz, which is ideal for maintaining a stable output voltage amidst fluctuations in the input voltage.
• Low Noise: Low output noise of only 40µV RMS, making it an excellent choice for noise-sensitive applications such as precision instrumentation and RF circuits.
• Adjustable Output: While the default output is set to 1.8V, it can be adjusted with external resistors for applications requiring different voltages.
• Thermal Protection: Integrated thermal shutdown and current limit protection mechanisms safeguard the device against overheating and overcurrent conditions.
• Stable with Low ESR Capacitors: Stable with ceramic capacitors as low as 10µF, providing flexibility in design and reducing the overall solution size.
