LT3029EDE#TRPBF Dual, Low Noise, Low Dropout Voltage Linear Regulator

The LT3029EDE#TRPBF is a high-performance, dual low dropout voltage linear regulator designed by Linear Technology, now part of Analog Devices. This regulator is capable of providing up to 500mA of output current per channel, and it offers a very low dropout voltage and low noise operation, making it an ideal choice for precision, sensitive analog circuits, and microprocessor-based systems.

Key Features:

• Low Noise: With an output noise as low as 20µVRMS over a 10Hz to 100kHz bandwidth, the LT3029 is perfect for noise-sensitive applications such as RF supply and audio circuitry.
• Dual Outputs: The device features two independent output voltages for dual supply applications, which can be set from 1.2V to 29.5V with external resistors.
• Low Dropout Voltage: The low dropout voltage of just 300mV at full load helps in maintaining regulation even with a low input-to-output voltage differential.
• High Output Current: Each output can supply 500mA, making it suitable for a wide range of applications.
• Stable with Low ESR Ceramic Capacitors: The LT3029 operates stably with ceramic output capacitors that have low equivalent series resistance (ESR), reducing the required board space and component cost.
• Protection Features: It includes overcurrent and overtemperature protection, safeguarding the device and the load under abnormal conditions.
