XC6501B231GR-G

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

The XC6501B231GR-G is a high-speed, low-noise CMOS LDO regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 2.3V with a maximum output current of 200mA. The device operates within an input voltage range of 1.4V to 6.0V and features internal phase compensation, allowing stable operation without an external load capacitor. It includes a CE pin for standby control, reducing supply current to less than 0.1μA. The part is housed in a USP-4 package and supports an operating ambient temperature range from -40°C to +85°C.

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

• Internal phase compensation enables stable output without requiring an external load capacitor.
• Built-in CL auto-discharge function rapidly discharges stored charge in the output capacitor when the CE pin is set to a low level.
• Fold-back current limit circuit provides short-circuit protection and limits output current during overload conditions.

• Smart phones
• Portable games
• Wireless modules
• Bluetooth devices
• Digital-TV tuners

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

Verify that the specific ordering suffix GR-G corresponds to the USP-4 package format as defined in the manufacturer's documentation. Confirm that the B-series designation indicates the presence of the CL discharge feature required for the application. Ensure compliance with RoHS standards is validated against the latest product specifications before finalizing procurement orders.

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

Select this component when a fixed 2.3V output is required with a maximum load of 200mA. The USP-4 package is suitable for space-constrained designs. The inclusion of the CL discharge feature makes it appropriate for applications requiring rapid power-down states. Verify that the input voltage remains within the 1.4V to 6.0V operational range under all expected conditions.

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

This component belongs to the XC6501 series of 200mA High Speed LDO Regulators. The series is characterized by low power consumption and the ability to operate stably without external output capacitors due to internal phase compensation. The B-type designation specifically denotes regulators equipped with a CL discharge switch controlled by the CE pin.

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

Does the XC6501B231GR-G require an external load capacitor?

No, the device utilizes internal phase compensation to ensure stable operation without an external load capacitor (CL).

What is the function of the CE pin in the XC6501B series?

The CE pin controls the ON/OFF state of the regulator. When set to a low level, it activates the internal auto-discharge switch to quickly drain charge from the output capacitor.
