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

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and taping orientation. Ensure the CE pin logic requirements match the design, as the 'A' series includes internal pull-down circuitry. Confirm RoHS compliance status directly with the supplier documentation prior to finalizing procurement orders.

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

Select this component when a fixed 1.3V output is required with high precision. The USP-6C package suits space-constrained designs. Ensure sufficient Vgs margin (VBIAS - VOUT) is maintained for optimal dropout performance. Verify that the load current does not exceed the thermal dissipation limits defined by the PCB layout conditions.

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

This part belongs to the XC6601 series of low voltage input LDO regulators. The series offers various output voltages selectable in 0.05V increments. The 'A' designation indicates the inclusion of an internal pull-down resistor on the CE pin, distinguishing it from the 'B' series which lacks this feature.

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

What is the purpose of the CL auto-discharge function?

It allows the IC to quickly discharge the electric charge at the output capacitor (CL) when the CE pin is set to low, preventing malfunction caused by residual voltage.

How does the soft-start function benefit the circuit?

It reduces the inrush current from VIN to VOUT during startup, helping to stabilize the input voltage source.
