SC4212B
Very Low Input /Very Low Dropout
1 Amp Regulator
Description
The SC4212B is a high performance linear voltage regula-
tor 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.
The SC4212B has an enable pin to further reduce power
dissipation while shut down. Protection features include
over current protection, over temperature protection and
reverse blocking from output to input. The SC4212B is
available in a 3mm x 3mm MLPD-8 package.
