• Product introduction

XC6601B121MR-G  对应低输入电压动作LDOVoltage regulator

The XC6601 series is a built-in N-channel FET with a 400mA output high-speed LDO voltage regulator. Even low output voltages allow efficient current output with ultra-low on-impedance. This series is suitable for applications with low input voltages and low input-output voltage differences.
The XC6601 series consists of a voltage reference, error amplifier, driver three-stage transistor, constant current limit circuit, FOLD-BACK circuit, overtemperature protection circuit (TSD), undervoltage lockout circuit (UVLO) and phase compensation circuit.
Through laser trimming technology, the output voltage range is 0.7V~1.8V, and the 0.05V interval is set. The output capacitor (CL) can be used with a low ESR type capacitor.
When the output current reaches the limit current or the junction temperature reaches the limit temperature, the overcurrent protection circuit (constant current limiting circuit, FOLD-BACK circuit) and overtemperature protection circuit (TSD) will work to protect the IC.
When the voltage between the VBIAS and VIN terminals is lower than the UVLO voltage, the output of the voltage regulator is turned off.
When the CE terminal input is low, the IC enters standby mode and the current consumption is greatly reduced. At the same time, when entering standby mode, the charge on the output capacitor (CL) can be released through an internal switch between the VOUT terminal and the VSS terminal, allowing the voltage to quickly return to the VSS level.
