XC6216B472ER-G

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

The XC6216B472ER-G is a positive fixed-output linear voltage regulator from the Torex XC6216 series. It provides a nominal output voltage of 4.7V with ±2% accuracy and supports a maximum output current exceeding 150mA. The device operates within an input voltage range of 2.0V to 28.0V and features a low supply current of 5μA. It includes built-in overcurrent protection and thermal shutdown circuits, ensuring reliable operation across an ambient temperature range of -40°C to +85°C.

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

• Integrated CE pin enables active high control for turning off the output and entering ultra-low standby mode.
• Built-in overcurrent limit and thermal shutdown circuits protect against overload and excessive junction temperatures.
• Compatible with low ESR ceramic capacitors for output stabilization without requiring additional bulk capacitance.

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

• Mobile devices and terminals
• Car audio and navigation systems
• Digital still cameras and camcorders

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

Verify the package type matches the design requirements, as the ER-G suffix indicates the USP-6C package. Confirm that the CE pin logic level aligns with the system control signals, as it requires a high voltage to activate. Ensure the PCB layout accommodates the bare pad for thermal dissipation if operating near maximum power limits.

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

Select this component when a stable 4.7V rail is required with minimal quiescent current consumption. The USP-6C package offers a compact footprint suitable for space-constrained portable electronics. Verify that the input voltage remains sufficiently above the output voltage to maintain regulation under all load conditions.

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

This part belongs to the XC6216 series of 28V low-power LDO regulators manufactured by Torex Semiconductor. The 'B' designation indicates a fixed output voltage configuration, while the '47' code specifies the 4.7V nominal setting. The series utilizes laser trimming technology to achieve precise voltage accuracy across the production batch.
