XC6204B542DR-G

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

The XC6204B542DR-G is a fixed positive voltage Low Dropout (LDO) regulator manufactured by Torex Semiconductor using CMOS processes. It provides a nominal output voltage of 5.4V with a maximum output current of 150mA. The device operates within an input voltage range of 2V to 10V and features a dropout voltage of 200mV at 100mA load. It includes built-in ON/OFF control functionality, high ripple rejection, and low power consumption characteristics suitable for portable applications.

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

• Built-in ON/OFF control circuit allows the output to be turned off via the CE pin, significantly reducing standby power consumption.
• Capable of maintaining output stability when used with low ESR ceramic capacitors due to integrated phase compensation.
• Incorporates a foldback current limiter that functions as a short-circuit protection mechanism for both the output current and the output pin.

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

• Smart phones
• Portable game consoles
• Digital still cameras
• Reference voltage sources

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

Verify the specific package type matches the design requirements, as the series supports multiple options including USP-6B. Confirm the CE pin logic level corresponds to the 'B' designation for active-high operation without internal pull-down resistors. Ensure compliance with environmental standards such as EU RoHS and lead-free specifications before finalizing procurement.

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

Select this component when a fixed 5.4V supply is required with moderate current demands up to 150mA. The B-series designation indicates active-high CE logic without internal pull-downs, requiring external circuit consideration if the control signal is floating. Verify that the input voltage remains within the 2V to 10V range to ensure proper regulation and performance.

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

This part belongs to the XC6204/XC6205 series of high-speed LDO regulators from Torex Semiconductor. The series is characterized by high precision, low noise, and fast transient response. The XC6204 variant specifically supports higher output currents compared to the XC6205, making it suitable for applications requiring stable power delivery in compact form factors.
