XC6503C23APR-G

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

The XC6503C23APR-G is a fixed-output CMOS LDO regulator from Torex Semiconductor, providing a nominal output voltage of 2.3V with ±1% accuracy. It supports a maximum output current of 500mA and operates within an input voltage range of 1.7V to 6.0V. The device features internal phase compensation for stable operation without external load capacitors. Key electrical parameters include a typical supply current of 15μA, dropout voltage of approximately 240mV at 300mA, and power supply rejection ratio of 55dB at 1kHz. It includes built-in thermal shutdown and fold-back current limit protection.

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

Verify the specific package type (SOT-89-5) and output tolerance against project requirements. Confirm that the CE pin logic level matches the control signal available in the design. Ensure compliance with RoHS standards as indicated by the -G suffix. Review absolute maximum ratings to prevent exceeding thermal or voltage limits during operation.

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

Select this component when a fixed 2.3V rail is required with high speed transient response. The C-type designation provides a pull-down resistor on the CE pin to prevent unstable operation if the pin is left open. Consider the SOT-89-5 package for its thermal dissipation capabilities relative to smaller packages like USP-4.

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

This part belongs to the XC6503 series of CL capacitor-less LDO regulators. The 'C' variant specifically includes a pull-down resistor on the Chip Enable pin. It is designed for portable electronics requiring low quiescent current and compact board space due to the elimination of external output capacitors.
