XC6501B19ANR-G

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

The XC6501B19ANR-G is a high-speed, low-noise CMOS LDO regulator from Torex Semiconductor. It provides a fixed output voltage of 1.9V 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 an SSOT-24 package.

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

• Internal phase compensation enables stable regulation without requiring an external output capacitor.
• Integrated CL auto-discharge function rapidly discharges stored charge in the output capacitor when the CE pin is set to 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 the specific ordering suffix NR-G corresponds to the SSOT-24 package configuration required for your design. Confirm that the B-series designation matches the need for the CL auto-discharge feature, as other series variants lack this function. Ensure the fixed 1.9V output aligns with the target load requirements before finalizing procurement.

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

Select this component when a fixed 1.9V output is required alongside space-saving benefits from eliminating the output capacitor. The B-series variant is specifically chosen for its ability to discharge output capacitance quickly upon shutdown. Consider the SSOT-24 package dimensions against available PCB real estate and verify thermal dissipation capabilities under expected load conditions.

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

This part belongs to the XC6501 series of 200mA High Speed LDO Regulators. The 'B' indicates it is a CE High Active type with CL discharge capability. The '19A' specifies the 1.9V output voltage with 0.05V increment precision. The 'NR-G' denotes the SSOT-24 package and RoHS compliance.

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

Does the XC6501B19ANR-G require an external output 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 on this regulator?

The CE pin controls the ON/OFF state. A high signal turns the regulator on, while a low signal activates standby mode and engages the internal auto-discharge switch to pull the output to VSS.
