XC6221C19A7R-G

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

The XC6221C19A7R-G is a fixed-output low dropout regulator from Torex Semiconductor, housed in an ultra-small USPN-4 package. It provides a nominal output voltage of 1.90 V with a standard accuracy tolerance of ±2%. The device supports a maximum continuous output current of 200 mA and operates within an input voltage range of 1.6 V to 6.0 V. Key electrical characteristics include a typical supply current of 25 μA and a standby current of 0.01 μA. It features a high ripple rejection rate of 70 dB at 1 kHz and includes an internal CE pin pull-down resistor.

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

• Integrates an internal pull-down resistor on the CE control pin to ensure defined logic states when the pin is left open.
• Utilizes laser trimming technology for precise factory-set output voltage selection in 0.05 V increments.
• Capable of driving low ESR ceramic capacitors directly without requiring additional bulk capacitance for stability.

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

• Smart phones
• Portable game consoles
• Digital still cameras
• Mobile devices

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

Verify the specific ordering suffix '7R-G' corresponds to the USPN-4 package configuration and reel quantity requirements. Confirm that the 'C' designation aligns with the required CE pin pull-down resistor functionality. Ensure the component meets EU RoHS compliance standards as indicated by the manufacturer's documentation.

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

Select this variant when a fixed 1.90 V rail is required alongside a compact footprint constraint. The internal pull-down resistor simplifies PCB layout by removing the need for external biasing components on the enable pin. Verify that the load current does not exceed the 200 mA limit under worst-case thermal conditions.

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

This component belongs to the XC6221 series of CMOS LDO regulators designed for portable electronics. The series offers various output voltages and package options, including USP-4, SOT-25, SSOT-24, and USPN-4. The C-type variants specifically feature an internal pull-down resistor on the CE pin, distinguishing them from A-type parts which lack this feature.
