FAN2514S27X

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

The FAN2514S27X is a fixed-output low-dropout voltage regulator from the FAN2514/15 family, manufactured by onsemi. It provides a nominal output voltage of 2.7 V with a maximum output current capability of 200 mA. The device utilizes CMOS technology and operates within an input voltage range of 2.7 V to 6.5 V. Key electrical parameters include a dropout voltage of 200 mV at full load (200 mA) and a ground pin current of 75 µA under the same conditions. The unit features thermal limiting protection that activates at a junction temperature of 150 °C. It is housed in a compact SOT-23-5 surface-mount package.

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

Verify the specific suffix 'S27X' confirms the 2.7 V fixed output configuration. Confirm the manufacturer designation as onsemi or Fairchild Semiconductor. Ensure the component is sourced from authorized distributors to guarantee authenticity, as the datasheet indicates this product line may be subject to integration changes. Check for RoHS compliance status if required by your manufacturing standards.

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

Select the FAN2514S27X when a fixed 2.7 V rail is required with up to 200 mA load current. This model is preferred over adjustable variants due to its integrated bypass pin for noise reduction. Consider the SOT-23-5 footprint constraints and ensure adequate copper area for thermal dissipation given the 200 mV dropout at maximum load. Verify input voltage remains above the minimum operating threshold during all system states.
