FAN2512SX

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

The FAN2512SX is a low-dropout (LDO) linear voltage regulator manufactured by onsemi. It provides a fixed output voltage of 2.7 V with a maximum continuous output current of 150 mA. The device operates within an input voltage range up to 6.5 V and features a typical dropout voltage of 2.5 mV at full load, with a maximum of 180 mV. It includes protection against over-temperature conditions and offers a power supply rejection ratio (PSRR) of 43 dB at 120 Hz. The component is housed in a compact SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +125°C.

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

Verify the specific suffix variant during procurement as the base model may have multiple output voltage options. Confirm RoHS compliance status and check for end-of-life notices since this component series has faced discontinuation risks. Ensure the ordering part number matches the required fixed voltage output exactly. Request official datasheets to validate pin configurations and thermal performance data before finalizing supply agreements.

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

Select this component when a fixed 2.7 V output is required with minimal voltage drop across the regulator. Consider the 150 mA current limit for loads that do not exceed this threshold. Evaluate the SOT-23-5 package size constraints against available PCB real estate. Compare PSRR specifications against noise sensitivity requirements of downstream circuitry to ensure signal integrity is maintained.

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

This LDO belongs to the FAN2513/FAN2512 family of low-power regulators designed for space-constrained applications. It shares architectural similarities with other members like the FAN2513S27X but differs in specific output voltage settings and packaging variants. The series targets cost-sensitive markets while maintaining reliability standards for general-purpose power management tasks in portable devices.

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

Direct substitutes include the FAN2513S27X for identical voltage and current specs in compatible packages. Verify pin compatibility and thermal resistance values when cross-referencing with other LDO families. Check manufacturer announcements for lifecycle changes affecting long-term availability.
