XC6221D36ANR-G

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

The XC6221D36ANR-G is a high-speed, low dropout CMOS voltage regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 3.6V with a maximum output current of 200mA. The device operates within an input voltage range of 1.6V to 6.0V and features a typical supply current of 25μA. Stand-by current is less than 0.1μA. It includes a CE function for active-high control and internal auto-discharge capability in standby mode. The unit is housed in an SSOT-24 package.

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

• Integrates a reference voltage source, error amplifier, current limiter, and phase compensation circuit for stable regulation.
• Features an internal auto-discharge switch that rapidly pulls the output voltage to the VSS level when the CE pin is set to low.
• Includes an internal pull-down resistor on the CE pin to prevent undefined states when the control signal is open.
• Compatible with low ESR ceramic capacitors for output stabilization.

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

How does the XC6221D36ANR-G handle the output capacitor charge during standby?

When the CE pin is driven low, the internal auto-discharge switch activates, discharging the electric charge from the output capacitor (CL) through an internal resistance to quickly return the VOUT pin to the VSS level.

What is the behavior of the CE pin if left unconnected?

The XC6221D series includes an internal pull-down resistor on the CE pin. If left open, the pin is pulled to the VSS level, placing the IC in the OFF state.
