Product Description

"Green Operation" LDO Regulator

The XC6237 is a truly revolutionary range of low noise, high speed, LDO regulators, which incorporate our proprietary ‘Green Operation’ (GO) functionality. Our GO circuit automatically reduces quiescent current at low output loads down to only 0.6μA (typ), whilst offering extremely fast ripple rejection (60dB @ 1kHz) and low dropout voltage (110mV @ 100mA) in high speed mode (HS).

Green operation (GO) automatically switches between a high speed mode (HS) and a power save mode (PS) depending upon the load current level. The switch point is fixed internally. 

The XC6237 is available in SOT-23, SSOT-24 and an ultra-small USPQ-4B05 package which measures 1.0 x 1.0 x 0.33mm.

Key Features:

  • Low Power Consumption:  0.6μA (typ.)
  • Stand-by Current less than 0.01μA
  • Maximum Output Current: 150mA 
  • Dropout Voltage: 110mV@ 100mA (HS Mode)
  • Operating Voltage Range: 1.6V ~ 6.0V
  • Output Voltage Setting Range 1.2V ~ 5.0V (50mV increments)
  • Fast Ripple Rejection 60dB @ 1kHz
