XC6227C271PR-G

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

The XC6227C271PR-G is a fixed-output linear regulator from the Torex XC6227 series, providing a nominal output voltage of 2.7V with a maximum continuous output current of 700mA. It operates within an input voltage range of 1.7V to 6.0V and features a typical dropout voltage of 120mV at 300mA load. The device incorporates reverse current protection, thermal shutdown, and over-current limiting. It utilizes a SOT-89-5 surface-mount package and is designed for low power consumption with a supply current of 100μA.

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

How does the reverse current protection function operate?

The circuit prohibits reverse current flow from the VOUT pin to the VIN pin when the output voltage is higher than the input voltage, suppressing the reverse current to a maximum of 1.5μA.

What is the effect of leaving the CE pin open on the C-type device?

For the C/E type devices like the XC6227C271PR-G, a pull-down resistor ensures the IC enters stand-by mode if the CE pin is left open, preventing undefined states.
