XC6221C16A7R-G

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

The XC6221C16A7R-G is a fixed-output low dropout regulator manufactured by Torex Semiconductor. It provides a nominal output voltage of 1.60 V with a standard accuracy tolerance of +2% for voltages above 1.50 V. The device supports a maximum output current of 200 mA and operates within an input voltage range of 1.6 V to 6.0 V. It features a typical ripple rejection rate of 70 dB at 1 kHz and maintains a supply current of 25 μA during operation, reducing to 0.01 μA in standby mode. The component utilizes a USPN-4 surface-mount package and includes an internal pull-down resistor on the CE pin.

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

What is the function of the internal pull-down resistor in the XC6221C series?

The internal pull-down resistor ensures that the IC turns off automatically if the CE pin is left open or disconnected, preventing undefined operational states.

How does the output voltage accuracy vary with voltage level?

For output voltages greater than 1.50 V, the standard accuracy is specified as +2%. For voltages at or below 1.45 V, the accuracy is specified as ±30 mV.
