SC4212LM High PSRR, Very Low Input, Very Low Dropout, 1A Linear Regulator HIGH-RELIABILITY PRODUCTS Features Description Input Voltage Range from 1.6V to 6.0V The SC4212LM is a high performance linear regulator 150mV Maximum Dropout 1A designed for applications requiring very low dropout Adjustable Output from 0.5V with 1% Accuracy voltage at load currents up to 1 Ampere. It operates with High PSRR (76dB Typical at 1.8Vin to 0.5Vo, 1A) VIN as low as 1.6V and up to 6V, making it useful for a wide Noise Bypass Pin range of different applications and rails. The output Programmable Soft-Start voltage is programmable down to 0.5V, set via an external 12A Quiescent Current in Shutdown resistor divider, or to a fixed setting of 0.5V depending Enable Input upon how the FB pin is configured. Power Good Indicator Over Current and Over Temperature Protection The SC4212LM has an enable pin to further reduce power Reverse Blocking from Output to Input dissipation while shut down. This device also offers an Military Temperature Range: -55C to +125C active-high power good for the system to check the 3mm x 3mm x 1mm MLPD-8 Package output voltage. An external soft start capacitor can be Fully WEEE and RoHS Compliant connected to the SS pin to program the profile of the startup. Additionally, the device provides protection fea- Applications tures such as over current protection, over temperature protection and reverse blocking from output to input. A Noise-sensitive rails capacitor at the BYP pin can bypass the noise generated in FPGA power the internal bandgap reference in order to improve the Embedded systems PSRR and the noise at the output. The SC4212LM is avail- Avionics able in a 3mm x 3mm MLPD-8 package.
