Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ILC7280AR3333X

ILC7280AR3333X

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

The ILC7280AR3333X is a dual low dropout (LDO) voltage regulator housed in an 8-pin MSOP package. It provides two independent 150mA outputs, both fixed at 3.3V. The device features 1% output voltage accuracy and a dropout voltage of 155mV to 180mV at full load. Quiescent ground current is 135µA at 150mA load. It includes over-current and thermal shutdown protection, with digital enable inputs for each regulator.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Dual independent 150mA LDO regulators with separate enable controls
Low noise performance with optional reference bypass pin
Integrated short circuit and thermal protection mechanisms
Stable operation with minimal external capacitance

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

Cellular phones and wireless headsets
Portable electronics such as PDAs and palmtops

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

Verify the specific suffix 'X' against manufacturer documentation to confirm tape-and-reel packaging requirements. Confirm that the 3.3V/3.3V configuration matches the design intent, as other voltage combinations exist within the family. Ensure input voltage stays within the 9V maximum rating during operation.

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

Select this component when dual isolated rails are required from a single supply source. The internal connection between VIN pins allows shared input but requires external connectivity for optimal performance. Consider the 0.47µF minimum output capacitor requirement for stability without noise bypassing.

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

This part belongs to the ILC7280 series of micropower dual LDOs originally manufactured by Fairchild Semiconductor. The series offers various voltage configurations including 3.0V, 2.8V, and mixed pairs. The AR3333X variant specifically denotes the 3.3V/3.3V output version in the MSOP-8 package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Other variants in the ILC7280 family share the same pinout and package. Substitutes must match the 3.3V output specification. Verify compatibility if different output voltages like 3.0V or 2.8V are acceptable alternatives.
