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

Select this component for applications requiring precise low-voltage regulation with minimal quiescent current. The B-series designation indicates no internal pull-down resistor on the CE pin, requiring external logic consideration. Ensure sufficient Vgs margin between VBIAS and VOUT for optimal dropout performance.

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

What is the purpose of the CE pin configuration in the A-series?

The XC6601A series includes an internal pull-down circuit on the CE pin, which fixes the logic state when the pin is open, unlike the B-series which requires external handling.

How does the soft-start function benefit the circuit?

The soft-start function limits the inrush current from VIN to VOUT during startup, stabilizing the input voltage and preventing potential system resets.
