XC6602B111ER-G

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

The XC6602B111ER-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 1.1 V with a maximum continuous current capability of 1 A. It operates within an input voltage range of 0.5 V to 3.0 V and supports a bias voltage range of 2.5 V to 6.0 V. The device features high accuracy of ±0.020 V for outputs at or above 1.2 V, though this specific variant falls slightly below that threshold where the tolerance is ±0.015 V. It includes built-in protection circuits such as thermal shutdown, under-voltage lockout, and fold-back current limiting. The component is housed in a USP-6C package and is designed for ceramic capacitor compatibility.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Features a Type B configuration which excludes the internal soft-start circuit found in Type A variants.
• Incorporates a CE pull-down function that automatically places the device in standby mode when the control pin is left open.
• Includes an auto-discharge mechanism that rapidly drains electric charge from the output capacitor upon entering standby mode.
• Provides comprehensive protection against over-temperature conditions via thermal shutdown and limits output current through a fold-back short-circuit protection circuit.

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

Verify the exact part number suffix ER-G corresponds to the USP-6C package format before ordering. Confirm that the Type B designation aligns with system requirements regarding the absence of a soft-start feature. Ensure that the fixed 1.1 V output voltage meets the target load specifications. Check that the operating temperature range covers the intended environmental conditions.

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

Select this component when a fixed 1.1 V output is required without the delay associated with a soft-start ramp-up. The Type B architecture offers faster transient response compared to Type A devices. Ensure sufficient VGS margin between the bias voltage and output voltage to maintain low on-resistance. Verify that the external ceramic output capacitor value meets the stability requirements specified in the datasheet.
