XC6501B33ANR-G

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

The XC6501B33ANR-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 3.3V with a maximum continuous current capability of 200mA. It 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. The device includes a control enable (CE) pin that activates the circuit at high logic levels and incorporates an auto-discharge function for the output capacitor when disabled. It maintains a typical supply current of 13μA during operation and reduces to less than 0.1μA in standby mode.

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

• Internal phase compensation eliminates the need for an external load capacitor while maintaining stability.
• Integrated CE pin enables rapid shutdown with an auto-discharge switch to quickly pull the output voltage to ground.
• Fold-back current limit circuit provides protection against short circuits and excessive output currents.

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

Verify the specific package designation NR-G corresponds to the SSOT-24 form factor required for your layout. Confirm the B-series designation ensures the presence of the CL discharge feature. Check RoHS compliance status as indicated by the -G suffix. Ensure the ordering information matches the exact voltage tolerance requirements for your application design.

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

Select this component when a compact footprint is prioritized over higher current capabilities. The SSOT-24 package offers a small surface-mount solution suitable for space-constrained designs. Consider the 200mA limit for loads exceeding this threshold. Verify that the 3.3V output aligns with downstream component voltage ratings. Evaluate the low quiescent current benefits for battery-powered portable applications.

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

This part belongs to the XC6501 series of high-speed CMOS LDO regulators manufactured by Torex Semiconductor. The series is characterized by its ability to operate stably without external output capacitors due to built-in phase compensation. The B-series variant specifically includes the CL discharge functionality controlled via the CE pin, distinguishing it from other series types like A or C.

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

Does the XC6501B33ANR-G require an external output capacitor?

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

How does the CE pin affect the output voltage when turned off?

When the CE pin is set to a low level, the internal auto-discharge switch activates, rapidly discharging any charge on the output line and pulling the VOUT pin to the VSS level.
