XC6503A401GR-G

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

The XC6503A401GR-G is a CL capacitor-less 500mA low power consumption high speed LDO regulator from Torex Semiconductor. It provides stable output voltages without external load capacitors due to internal phase compensation. The device features a fixed output voltage of 4.0V with an accuracy of ±1% for outputs between 2.0V and 5.0V. It operates within an input voltage range of 1.7V to 6.0V and supports an operating ambient temperature range of -40°C to 85°C.

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

Verify the specific package type USP-4 and the -G suffix compliance against the official datasheet before procurement. Confirm that the ordering code matches the required output voltage and accuracy specifications. Ensure the component meets environmental standards as indicated in the manufacturer documentation.

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

Select this component when a compact footprint is required, as it eliminates the need for external output capacitors. The integrated chip enable pin makes it suitable for battery-powered applications requiring power management. Verify that the load conditions do not exceed the startup limitations defined in the notes section regarding load resistance and current.

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

This part belongs to the XC6503 series of CMOS LDO regulators designed for high-speed performance and low power consumption. The 'A' designation indicates the presence of a chip enable function without a pull-down resistor on the CE pin. The 'GR-G' suffix specifies the USP-4 package format and halogen-free, RoHS-compliant construction.

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

Direct replacements must match the USP-4 package and 4.0V output. Other XC6503 variants (B, C, D) offer different CE pin configurations such as pull-down resistors or auto-discharge capabilities. Ensure any substitute maintains the same electrical characteristics and protection features.
