LT1962EMS8#TRPBF - Low Noise, Low Dropout Linear Regulator

The LT1962EMS8#TRPBF is a high-performance low dropout linear regulator (LDO) designed and manufactured by Linear Technology, now part of Analog Devices. This regulator is specifically engineered to deliver a low noise power supply solution with a minimal dropout voltage. It is an ideal choice for noise-sensitive applications such as precision instrumentation, data acquisition systems, and high-end audio equipment.

Key Features

• Output Voltage Range: The device provides a wide range of adjustable output voltages from 1.2V to 20V, which can be set using external resistors. This flexibility makes it suitable for a variety of applications that require different voltage levels.
• Low Dropout Voltage: With a low dropout voltage of typically 300mV at full load, the LT1962EMS8#TRPBF ensures efficient operation even when the input voltage is close to the output voltage, thereby maximizing battery life in portable applications.
• High Output Accuracy: The output voltage accuracy is maintained within ±0.8% over line, load, and temperature variations, ensuring a reliable and consistent power supply.
• Low Noise: The LT1962EMS8#TRPBF boasts an exceptionally low output noise of only 20μV RMS over a 10Hz to 100kHz bandwidth, making it an excellent choice for sensitive RF and precision analog circuits.
• Stable with Low ESR Ceramic Capacitors: The regulator is stable with ceramic output capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) compared to other types.
• Thermal Protection: The device features internal thermal limit circuitry that protects the regulator under overload conditions by limiting the junction temperature.

Package and Reliability
