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

Verify the specific package type USP-4 and the 2.6V fixed output voltage against project requirements. Confirm that the B-series designation matches the required CE pin pull-up resistor configuration. Ensure compliance with EU RoHS standards as indicated by the -G suffix before finalizing procurement specifications.

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

Select this component when a fixed 2.6V rail is needed with high speed transient response. The B-series variant is suitable for designs requiring a pull-up resistor on the CE pin rather than an internal one. Consider the 500mA output capability and low dropout characteristics for battery-powered applications operating near minimum input voltages.

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

This part belongs to the XC6503 series of CL capacitor-less LDO regulators. The series offers various output voltages in 0.05V increments. The XC6503B variant specifically distinguishes itself by utilizing an external pull-up resistor for the Chip Enable (CE) pin, unlike other series members that may have internal resistors or none at all.

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

How does the XC6503B series handle the CE pin state?

The XC6503B series requires an external pull-up resistor connected to the CE pin to ensure proper operation, distinguishing it from variants with internal pull-down or pull-up resistors.

Is an output capacitor required for stability?

No, the device utilizes internal phase compensation to maintain stability even without an external load capacitor (CL), although using one can improve transient response.
