XC6222B501PR-G

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

The XC6222B501PR-G is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Torex Semiconductor Ltd. It provides a stable 5 V output with a maximum continuous current of 700 mA. The device operates within an input voltage range of 1.7 V to 6 V and features a typical dropout voltage of 120 mV. Key electrical specifications include a quiescent current of 100 µA, a power supply rejection ratio (PSRR) of 65 dB at 1 kHz, and line regulation of 0.01 %/V. It is housed in a surface-mount SOT-89-5 package and supports an operating temperature range from -40 °C to +85 °C.

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

• Integrated reverse current protection circuit prevents backflow from output to input when the input voltage drops below the output voltage.
• High-speed transient response capability ensures rapid stabilization during load changes, suitable for dynamic power applications.
• Built-in overcurrent protection and thermal shutdown mechanisms safeguard the device against short circuits and excessive heat generation.

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

• Backup power supply circuits requiring high stability and low noise

• Embedded systems needing regulated 5 V logic levels

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

Verify the specific suffix 'PR-G' corresponds to the SOT-89-5 package and RoHS compliance status as defined in the official Torex datasheet. Confirm that the 'B' series designation aligns with the required output tolerance and performance characteristics for your design. Ensure ordering documentation references the correct manufacturer part number to avoid substitution errors.

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

Select this component when a fixed 5 V output is required with up to 700 mA load capacity. The low dropout voltage makes it suitable for inputs close to the output level. Consider the 100 µA quiescent current for battery life optimization. Verify thermal dissipation requirements based on the SOT-89-5 package power handling capabilities under expected ambient conditions.
