XC6503D161GR-G

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

The XC6503D161GR-G is a fixed-output low dropout regulator from Torex Semiconductor, providing a nominal output voltage of 1.6V with a maximum continuous current of 500mA. It operates within an input voltage range of 1.7V to 6.0V and maintains high accuracy of ±1% for voltages between 2.0V and 5.0V, while lower voltages like 1.6V are regulated within ±20mV. The device features internal phase compensation, allowing stable operation without external load capacitors. It includes built-in protection mechanisms such as current limiting, short-circuit protection, and thermal shutdown. The unit is housed in a USP-4 package.

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

Verify the specific suffix GR-G corresponds to the USP-4 package format when sourcing. Confirm that the D-type designation ensures the presence of both the pull-down resistor on the CE pin and the CL discharge function. Ensure compliance requirements match the Halogen and Antimony-free status indicated by the -G suffix.

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

Select this component for designs requiring a fixed 1.6V rail with high speed response. The D-series variant is necessary if automatic output capacitor discharge or a default-off state upon floating the control pin is required. Verify that the 500mA output capability meets the peak load demands of the target circuitry.

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

Does the XC6503D161GR-G require an external output capacitor?

No, the device utilizes internal phase compensation to ensure stability even without an external load capacitor.

What happens to the output voltage when the CE pin is left open?

Due to the internal pull-down resistor characteristic of the D-series, leaving the CE pin open will cause the IC to turn off.
