FAN2512S27X

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

The FAN2512S27X is a fixed-output low-dropout (LDO) voltage regulator manufactured by onsemi, formerly Fairchild Semiconductor. It provides a fixed 2.7 V output with a maximum load current of 150 mA. The device utilizes CMOS technology and features fast start-up capability enabled by an external capacitor. It operates within an input voltage range up to 6.5 V and maintains regulation across a junction temperature range of -40°C to +125°C. Key electrical specifications include a line regulation of 0.3%/V, load regulation of 2%, and a dropout voltage of 180 mV at full load. The component is housed in a compact SOT-23-5 surface-mount package.

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

Verify the manufacturer status as the part is listed as obsolete or discontinued by onsemi/Fairchild. Confirm availability through authorized distributors or secondary markets. Ensure the SOT-23-5 package matches the PCB footprint requirements. Check for RoHS compliance documentation if required for specific manufacturing standards.

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

Select this component when a fixed 2.7 V rail is required with moderate current demands up to 150 mA. The SOT-23-5 package suits space-constrained designs. Consider the fast start-up feature if rapid system initialization is necessary. Verify that the input voltage does not exceed the 6.5 V maximum rating under all operating conditions.

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

This component belongs to the FAN2512/13 family of micropower LDO regulators. These devices are designed to offer high performance in portable applications. The series shares similar architectural features but varies in output current ratings and specific voltage options. The FAN2512 variant typically supports higher currents compared to other members like the FAN2519.

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

Direct substitutes may include other parts from the FAN2512 series with different voltage outputs, such as FAN2512S25X or FAN2512S33X, provided the voltage requirement changes. Cross-referencing with equivalent LDOs from other manufacturers requires matching the SOT-23-5 package, 150 mA current rating, and 2.7 V output.
