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

Verify the specific ordering suffix and manufacturer part number against official documentation before procurement. Confirm that the component status aligns with project requirements, as this item may be designated as not recommended for new designs. Ensure compatibility with the required VCSP60N1-4 package footprint and verify RoHS compliance details through the manufacturer's datasheet prior to finalizing purchase orders.

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

Select this regulator when a fixed 2.8 V output is required with a maximum load current of 150 mA. Consider the 2.2 V minimum input voltage constraint and the 100 mV typical dropout voltage for headroom calculations. The 63 dB PSRR makes it suitable for applications sensitive to power supply noise. Evaluate the thermal performance based on the 530 mW power dissipation limit and the specific PCB layout capabilities for the VCSP60N1-4 package.
