LT3060EDC-3.3#TRPBF

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LT3060EDC-3.3#TRPBF is a micropower, low dropout linear regulator manufactured by Analog Devices Inc. It provides a fixed 3.3V output with a maximum current of 100mA and operates over an input voltage range of 1.6V to 45V. The device features a typical quiescent current of 40µA and a shutdown current of less than 1µA. It utilizes a single external capacitor for soft-start and noise reduction, achieving 30µVRMS noise from 10Hz to 100kHz. The component is housed in an 8-lead (2mm × 2mm × 0.75mm) DFN package and supports an operating junction temperature range of -40°C to 125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix #TRPBF corresponds to tape and reel packaging when sourcing components. Confirm that the E-grade designation aligns with the required -40°C to 125°C operating temperature range for your application environment. Ensure compatibility with the 8-lead DFN footprint during PCB layout verification.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this part for applications requiring high input voltage tolerance up to 45V combined with low quiescent current consumption. The fixed 3.3V output eliminates the need for external resistor dividers found in adjustable versions. Consider the thermal characteristics of the DFN package when designing for high ambient temperatures or continuous full-load operation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

Does the LT3060EDC-3.3#TRPBF require additional ESR for stability?

No, the LT3060 regulators are optimized for stability with low ESR ceramic output capacitors and do not require the addition of ESR.

What is the function of the SHDN pin on this regulator?

The SHDN pin controls the shutdown state; pulling it below the threshold reduces quiescent current to less than 1µA and resets the reference soft-start capacitor.
