XC6220D37BPR-G

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

The XC6220D37BPR-G is a CMOS low dropout regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 3.7V with a maximum continuous output current of 1A. The device operates within an input voltage range of 1.6V to 6.0V and features Green Operation technology for automatic switching between high-speed and power-save modes. It utilizes a SOT-89-5 package and includes built-in thermal shutdown, over-current protection, and CL auto-discharge capabilities.

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

• Green Operation function automatically switches between high-speed and power-save modes based on load current to minimize power consumption.
• Built-in CL auto-discharge circuit rapidly discharges the output capacitor when the control pin is deactivated.
• Integrated inrush current prevention circuit limits startup surge currents to protect the system.
• CE pull-down resistor ensures the IC enters standby mode if the control pin is left open.
