LT1965EDD-2.5#PBF

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

The LT1965EDD-2.5#PBF is a low noise, low dropout linear regulator from Analog Devices Inc., housed in an 8-lead (3mm × 3mm) plastic DFN package with an exposed ground pad. It provides a fixed regulated output voltage of 2.5V and supplies up to 1.1A of output current. The device features a typical dropout voltage of 310mV at full load and operates with a quiescent current of 600µA. It supports input voltages ranging from 3V to 20V and includes a shutdown pin for power management.

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

Verify the specific suffix #PBF indicates lead-free finish and RoHS compliance when sourcing. Confirm the E-grade designation corresponds to the –40°C to 125°C operating junction temperature range required for your application environment. Ensure the DFN package thermal requirements are met via proper PCB soldering to the exposed pad.

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

Select this component when a fixed 2.5V rail is needed with high current capability in a compact footprint. Consider the DFN package for its thermal performance relative to size compared to MSOP or DD-Pak variants. Evaluate the need for the shutdown feature; if not required, other series members may suffice. Verify that the input voltage range aligns with your system's supply characteristics.
