Semtech SC4212B

Very Low Input /Very Low Dropout 1 Amp Regulator

Add to Watch List

The SC4212B is a high performance linear voltage regulator designed for applications requiring very low dropout voltage at load currents up to 1 Ampere. It operates with VIN as low as 1.6V and up to 6V, making it useful for a wide range of different applications and rails. The output voltage is programmable down to 0.5V, set via an external resistor divider, or to a fixed setting of 0.5V depending upon how the FB pin is configured.


  • Input Voltage Range from 1.6V to 6.0V
  • 150mV Maximum Dropout @ 1A
  • Adjustable Output from 0.5V with ± 1% Accuracy
