XC6501B211GR-G

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

The XC6501B211GR-G is a high-speed, low-noise CMOS LDO regulator from Torex Semiconductor. It provides a fixed 2.1V output with a maximum current of 200mA. The device operates within an input voltage range of 1.4V to 6.0V and features internal phase compensation, allowing stable operation without an external load capacitor. It includes a CE pin for standby control, reducing supply current to less than 0.1μA. The part utilizes a USP-4 package and supports an operating temperature range of -40°C to +85°C.

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

How does the XC6501B series handle output capacitor discharge?

The XC6501B series includes an internal auto-discharge switch that connects the output to ground when the CE pin is set to a low level, ensuring the output voltage quickly returns to the VSS level.

What is the function of the CE pin in this regulator?

The CE (Chip Enable) pin controls the ON/OFF state of the regulator. A high-level signal activates the circuit, while a low-level signal puts the device into standby mode, significantly reducing current consumption.
