FAN1538PAX

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

The FAN1538PAX is a dual-channel low dropout linear regulator manufactured by Fairchild Semiconductor. It provides two independent output voltages, specifically a fixed 3.3V output and either a fixed 2.5V or an adjustable output channel. Each channel supports an output current capability of 1A. The device is designed for applications requiring stable, low-noise power supply regulation with high line and load regulation characteristics.

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

Verify the specific suffix configuration to confirm whether the second output channel is fixed at 2.5V or adjustable, as this determines functional compatibility. Ensure the package type matches the target PCB footprint requirements. Confirm RoHS compliance status if environmental regulations apply to the end product assembly process.

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

Select this component when a single IC solution is required to generate two distinct regulated voltages from a single input source. It is suitable for designs where space constraints prevent using separate regulators for each rail. Consider the thermal dissipation requirements based on the input-output voltage differential and total load current to ensure reliable operation within specified temperature ranges.

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

This part belongs to the FAN1538 series of dual-channel linear regulators. It is categorized under analog mixed-signal integrated circuits. The manufacturer, Fairchild Semiconductor, utilizes advanced processes to ensure stability and performance in compact packages suitable for modern electronic assemblies requiring multi-rail power distribution.

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

Direct substitutes may include other dual-channel LDOs from Fairchild or equivalent manufacturers offering similar 1A per channel ratings and compatible pinouts. Verify that replacement parts maintain the same output voltage configurations (3.3V and 2.5V/Adjustable) and package dimensions to ensure mechanical and electrical interchangeability without circuit redesign.
