LT3066EDE-3.3#TRPBF

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

The LT3066EDE-3.3#TRPBF is a micropower, low noise, low dropout voltage (LDO) linear regulator manufactured by Analog Devices Inc. It operates over an input voltage range of 1.6V to 45V and supplies up to 500mA of output current with a typical dropout voltage of 300mV. The device provides a fixed regulated output voltage of 3.3V with an output tolerance of ±2% over line, load, and temperature conditions. Key electrical specifications include a shutdown current of less than 3µA, programmable precision current limit accurate to ±10%, and a power good flag. It features active output discharge via an NMOS pull-down and internal protections including thermal limiting, reverse battery protection, and reverse current protection.

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

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing. Confirm the E-grade designation matches the required operating junction temperature range of –40°C to 125°C for your application environment. Ensure the DFN package dimensions align with your PCB footprint requirements before finalizing procurement.

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

Select this component for applications requiring high input voltage stability up to 45V and precise current limiting. The fixed 3.3V output eliminates the need for external resistor dividers, simplifying design. Consider the 12-lead DFN package for its thermal performance and compact size in space-constrained layouts.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the LT3066 series of LDO regulators from Analog Devices. It shares core architectural features with other variants in the family, such as the adjustable version and the MSOP package option. The primary distinctions are the fixed 3.3V output voltage and the specific 12-lead 4mm × 3mm plastic DFN package configuration.
