Introduced the selection and application of multi-function VDR, including input voltage range, operating current, output voltage range, output voltage accuracy, transient response, ripple rejection, maximum output current, limiting current, short circuit current, on-resistance, detect voltage range, detect voltage accuracy, delay voltage, output type, delay function type, EN function type, CE function type, CE/EN, CE/EN pull-up resistor, package type, PIN definition, and wafer substrate type.
The XC6402 series from Torex are low‑power voltage‑regulation ICs designed for portable devices such as mobile phones, cameras and handheld consoles. They offer selectable functions like EN, CE, VSEN and external delay, and are supplied in SOT‑89‑5 packages.\n\nKey specifications include input voltage ranges from 1.5 V to 6.0 V, output voltages from 0.8 V to 5.6 V, maximum output currents up to 700 mA, ripple rejection of up to 60 dB at 1 kHz, and on‑resistance of 0.5 Ω at 3 V. This manual is written in Chinese.

The input voltage range is 1.5 V to 6.0 V for the XC6402 model and 2.0 V to 6.0 V for other models.
The XC6402 can deliver up to 700 mA, while other models provide between 300 mA and 500 mA.
They are offered in a 5‑lead SOT‑89‑5 package.
Typical ripple rejection is 60 dB at 1 kHz for the XC6402 and 55 dB for other variants.
