XC6221C24ANR-G

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

The XC6221C24ANR-G is a fixed positive linear low-dropout (LDO) voltage regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 2.40V with a maximum output current capability of 200mA. The device features a maximum input voltage rating of 6V and operates within an ambient temperature range of -40°C to +85°C. Key electrical specifications include a typical quiescent current of 25µA, a dropout voltage of approximately 0.195V at full load, and a power supply rejection ratio (PSRR) of 60dB at 1kHz. The unit is housed in an SSOT-24 package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated enable control function allows the device to enter a low-power standby state via a low-level signal input.
• Internal auto-discharge circuit rapidly discharges output capacitor charge when disabled, ensuring the output voltage quickly returns to ground level.
• Fold-back current limiter protects against short circuits and limits output current under overload conditions.
• Compatible with low equivalent series resistance (ESR) ceramic capacitors for stable operation.

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

Verify the specific suffix 'C' corresponds to the required 2.40V output voltage, as other letters indicate different factory-trimmed voltages. Confirm the 'ANR-G' designation matches the required SSOT-24 surface-mount package and reel packaging format. Ensure the component meets RoHS3 compliance requirements for your assembly process.

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

Select this part when a precise 2.40V rail is needed from a source up to 6V. The 200mA current rating suits moderate load applications. Consider the 25µA quiescent current for battery efficiency. Verify that the 60dB PSRR at 1kHz meets the noise sensitivity requirements of the downstream circuitry.

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

How does the XC6221C24ANR-G behave when the enable pin is deactivated?

When the enable pin receives a low-level signal, the IC enters standby mode. For the 'C' type, the internal auto-discharge switch activates to discharge the output capacitor, causing the output voltage to drop rapidly to the VSS level.

What is the minimum input voltage required for proper regulation?

The minimum input voltage is determined by the output voltage plus the dropout voltage. For a 2.40V output, the input must remain above the dropout threshold (approx. 0.195V at 200mA) to maintain regulation, typically requiring an input slightly above 2.6V under full load.
