LT3002ES8E#TRPBF

Overview

The LT3002ES8E#TRPBF is a low dropout linear regulator manufactured by Analog Devices Inc., housed in an SO-8 package. It provides a fixed output voltage of 1.25V with a maximum output current of 20mA. The device supports an input voltage range from 1.2V to 45V and operates within a temperature range of -40°C to +125°C. Key electrical specifications include a quiescent current of 6µA, a typical power supply rejection ratio (PSRR) of 70dB at 120Hz, and a maximum dropout voltage of 300mV at full load. It features internal protection against overcurrent, thermal overload, and reverse polarity.

Feature Summary

• Fixed 1.25V output voltage eliminates external resistor networks for setting the output level.
• Capacitor-free stability allows operation with only ceramic output capacitors, simplifying design.
• Integrated protection mechanisms include overcurrent limiting, thermal shutdown, and reverse polarity blocking.

Applications

• Battery-powered portable devices requiring low quiescent current
• Noise-sensitive analog circuits needing clean power rails
• Embedded systems with limited board space due to compact packaging

Procurement Notes

Verify the exact part number LT3002ES8E#TRPBF against official Analog Devices documentation to confirm the fixed 1.25V output and SO-8 package configuration. Ensure compatibility with your system's input voltage range and thermal requirements before procurement. Check for RoHS compliance status as indicated in the manufacturer's datasheet.

Selection Notes

Select this component when a stable 1.25V rail is required with minimal external components. It is suitable for applications prioritizing low noise and high PSRR over adjustable voltage flexibility. Consider the 20mA output limit and ensure it meets the load current demands of the target circuit.

Part Context

This part belongs to the LT3002 series of low dropout linear regulators from Analog Devices. It is designed for applications requiring high performance in a small footprint. The ES8E suffix indicates the specific package type and temperature grade, distinguishing it from other variants in the family.

Replacement Considerations

Consult Analog Devices documentation for direct pin-compatible alternatives within the LT3002 or LT3008 series that match the 1.25V output and SO-8 package. Verify electrical parameters such as output current and PSRR to ensure functional equivalence.
