Semtech SC4212LM
The SC4212LM is a high performance linear 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.
The SC4212LM has an enable pin to further reduce power dissipation while shut down. This device also offers an active-high power good for the system to check the output voltage. An external soft start capacitor can be connected to the SS pin to program the profile of the startup. Additionally, the device provides protection features such as over current protection, over temperature protection and reverse blocking from output to input. A capacitor at the BYP pin can bypass the noise generated in the internal bandgap reference in order to improve the PSRR and the noise at the output. The SC4212LM is available in a 3mm x 3mm MLPD-8 package.
