XC6701B272MR-G

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

The XC6701B272MR-G is a positive voltage regulator IC from Torex Semiconductor, featuring a 28V operation range and a fixed 2.7V output with ±2.0% accuracy. It delivers over 150mA of output current with a typical dropout voltage of 310mV at 20mA. The device operates within an ambient temperature range of -40℃ to 85℃ and includes built-in current limit and thermal protection circuits. It utilizes internal phase compensation for ceramic capacitor compatibility and offers a stand-by mode via the CE pin.

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

What happens if the CE pin is left open?

Leaving the CE pin open results in undefined operation and potential instability. It must be connected to either VIN or VSS to ensure proper functionality.

Is an output capacitor required for stability?

While the IC features internal phase compensation allowing operation without an output capacitor, placing one between 0.1μF and 1.0μF is recommended to control output voltage fluctuations during load changes.
