LT3024IFE#PBF

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

The LT3024IFE#PBF is a dual micropower, low noise, low dropout regulator from Analog Devices Inc. It features two independent outputs: Output 1 supplies up to 500mA and Output 2 supplies up to 100mA. Both outputs operate within an input voltage range of 1.8V to 20V with a typical dropout voltage of 300mV at full load. The device offers adjustable output voltages from 1.22V to 20V using external resistors. Quiescent current is 30μA per output, dropping below 0.1μA in shutdown. Noise is reduced to 20μV RMS (10Hz to 100kHz) with a 0.01μF bypass capacitor.

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 'IFE' designation corresponds to the 16-lead TSSOP package variant. Ensure the ordering code matches the required temperature grade for your application environment. Cross-reference the manufacturer's latest documentation for any potential product change notifications or obsolescence notices before finalizing procurement plans.

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

Select this component for applications requiring high current density in a small footprint with strict noise constraints. The 16-lead TSSOP package provides thermal enhancement suitable for dense PCB layouts. Consider the independent shutdown pins if separate power sequencing or standby modes are required for different subsystems. Verify that the minimum output capacitance requirements align with your transient load specifications.

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

This part belongs to the LT3024 family of dual LDO regulators designed for battery-operated electronics.
