FAN1540MPX

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

The FAN1540MPX is a fixed-output linear regulator manufactured by onsemi, designed for applications requiring stable voltage regulation. It provides a fixed output of 3.3V with a maximum continuous output current of 1.3A. The device operates from an input voltage range up to a maximum of 10V. Key electrical specifications include a maximum dropout voltage of 1.2V at full load and a quiescent current (Iq) of 2 mA. Power supply rejection ratio (PSRR) ranges from 75dB to 57dB at 120Hz. The component is housed in a compact 6-MLP (3x3) surface-mount package.

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

Verify the specific suffix variant against official datasheets, as packaging or temperature grades may differ. Confirm availability status, as this part number may be discontinued or subject to last-time buy restrictions. Ensure the selected package matches the PCB footprint requirements for 6-MLP (3x3) components. Cross-reference ordering information with authorized distributors to avoid counterfeit parts.

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

Select this component when a fixed 3.3V rail is required with up to 1.3A load capability. Consider the 10V maximum input voltage limit during system design. Evaluate the 1.2V dropout voltage to ensure sufficient headroom between input and output under all operating conditions. The 2 mA quiescent current should be assessed against total system power budgets.

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

The FAN1540 series belongs to onsemi's portfolio of linear regulators (LDOs). These devices are categorized under PMIC solutions for general-purpose voltage regulation. The FAN1540MPX specifically utilizes a 6-MLP package, distinguishing it from other pinout variants within the same functional family.

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

Check for direct cross-references in distributor databases. Verify that any substitute maintains the 3.3V fixed output, 1.3A current rating, and compatible 6-pin MLP package dimensions.
