XC6503A141GR-G

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

The XC6503A141GR-G is a CMOS LDO regulator from Torex Semiconductor, providing a fixed 1.4V output with ±1% accuracy. It supports up to 500mA output current within a 1.7V to 6.0V input range. The device operates without an external load capacitor due to internal phase compensation. Key electrical parameters include a typical supply current of 15μA and a dropout voltage of approximately 280mV at 300mA. It features fold-back current limiting, short-circuit protection, and thermal shutdown.

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

Verify the specific suffix GR-G indicates USP-4 packaging in reels of 3000 units. Confirm the 'A' designation matches the required 0.05V increment output voltage setting. Ensure compliance with EU RoHS standards as indicated by the manufacturer's documentation.

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

Select this component when board space optimization is critical, as it eliminates the need for external output capacitors. The integrated CE pin allows for system-level power control. Verify that the 1.4V output aligns with the target circuit requirements and that the 500mA capacity meets peak load demands.

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

This part belongs to the XC6503 series of high-speed CMOS LDO regulators. The series offers various output voltages and package options including SOT-25 and SOT-89-5. The 'A' type specifically includes a Chip Enable pin but lacks the internal pull-down resistor found in C/D types.

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

Direct substitutes within the same series include XC6503B141GR-G (with pull-down resistor) or XC6503C141GR-G (with pull-down resistor). Other packages like MR-G (SOT-25) are electrically compatible if pinout alignment is verified.
