XC6701A972ER-G

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

The XC6701A972ER-G is a positive fixed-output linear voltage regulator from the XC6701 series, manufactured by Torex Semiconductor. It provides a nominal output voltage of 9.7V with ±2.0% accuracy and supports a maximum output current exceeding 150mA. The device operates within an input voltage range of 2.0V to 28.0V and features a Chip Enable (CE) function for standby control. It utilizes a USP-6C package and is rated for an operating ambient temperature range of -40°C to +105°C.

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

Verify the specific ordering suffix ER-G corresponds to the USP-6C package configuration. Confirm that the CE pin is properly biased to avoid undefined states, as open pins may cause instability in the A-series regulators. Ensure compliance with RoHS standards if required by the target application environment.

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

Select this component when a fixed 9.7V output is required with high accuracy and wide input voltage tolerance. The USP-6C package suits applications needing compact surface-mount solutions. Consider the extended temperature range up to 105°C for automotive or industrial environments where standard commercial grades are insufficient.

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

This part belongs to the XC6701 series of 28V operation high-speed voltage regulators. The 'A' designation indicates the -40°C to +105°C temperature grade, while '97' specifies the 9.7V output voltage. The '2' denotes ±2.0% accuracy, and 'ER-G' identifies the USP-6C package with halogen-free compliance.

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

What is the purpose of the CE pin on the XC6701A972ER-G?

The CE (Chip Enable) pin controls the ON/OFF state of the regulator. Applying a high level activates the output, while a low level enters standby mode. Leaving it open is undefined and may cause instability.

Can the XC6701A972ER-G operate without an output capacitor?

Yes, the IC includes internal phase compensation, allowing it to remain stable even without an external output capacitor, though a small ceramic capacitor is recommended for transient response.
