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

Verify the specific package type SOT-89-5 and the CE pin configuration (High Active with pull-down) match the design requirements. Confirm that the output voltage tolerance of ±2% aligns with system specifications. Ensure proper thermal management is planned for the selected PCB mounting condition.

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

Select this component when a stable 2.70V rail is required with high current capability up to 700mA. The A-type designation ensures the control enable function activates with a high signal and includes a pull-down resistor for defined standby states. Verify input voltage headroom against the specified dropout characteristics for the expected load current.

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

This part belongs to the XC6210 series of positive voltage low dropout regulators fabricated using CMOS process. The series offers selectable output voltages in 0.05V increments. The XC6210A variant specifically utilizes High Active logic for the Control Enable pin, distinguishing it from B, C, and D types which vary in active level and pull-up/down resistor presence.

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

What is the behavior of the output voltage when the CE pin is in standby mode?

In standby mode, the output at the VOUT pin is pulled down to the VSS level via the internal resistors R1 and R2.

How does the current limiter protect the circuit during a short circuit?

The IC uses a foldback circuit; as output voltage drops due to current limiting, the output current decreases further, resulting in approximately 50mA flow during a short circuit.
