XC6209B232DR-G

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

The XC6209B232DR-G is a positive voltage Low Dropout (LDO) regulator manufactured by Torex Semiconductor using CMOS processes. It provides a fixed output voltage of 2.3V with a maximum output current of 150mA. The device operates within an input voltage range of 2.0V to 10V and features a typical standby current of 0.01μA. It includes an ON/OFF control function via the CE pin, which is active high without a built-in pull-down resistor. The regulator offers high ripple rejection of 70dB at 10kHz and maintains stability with low ESR ceramic capacitors.

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

Verify the specific package type USP-6B and the CE pin logic configuration (Active High, no pull-down) against the design requirements. Confirm compliance with EU RoHS and Halogen-free standards indicated by the -G suffix. Ensure the input capacitor is placed close to the VIN pin to maintain stability.

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

Select this component when a fixed 2.3V output is required with a 150mA current capacity. The Type B designation indicates an Active High CE pin without an internal pull-down resistor; external biasing or connection to VIN/VSS is necessary to prevent unstable operation. Verify dropout voltage requirements against the load current conditions.

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

This part belongs to the XC6209 series of high-speed LDO regulators from Torex Semiconductor. The series utilizes CMOS technology to achieve low noise and high precision. The 'B' suffix denotes the standard 150mA type with an Active High enable pin lacking a pull-down resistor, while 'DR-G' specifies the USP-6B surface-mount package with environmental compliance.

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

How does the CE pin behave if left open?

For the Type B configuration, the CE pin has no internal pull-down resistor. Leaving it open may cause unstable operations; it should be connected to either VIN or VSS.

What is the recommended output capacitor type?

The series is compatible with low ESR ceramic capacitors. A capacitance value of at least 1μF is suggested for stable phase compensation.
