Texas Instruments LP38798 800mA Linear Regulator

Texas Instruments LP38798 Linear Regulator is a high-performance device capable of supplying 800mA output current. Designed to meet the requirements of sensitive RF/Analog circuitry, TI LP38798-ADJ implements a novel linear topology on an advanced CMOS process to deliver ultra-low output noise and high PSRR at switching power supply frequencies. LP38798SD-ADJ is stable with both ceramic and tantalum output capacitors and requires a minimum output capacitance of only 1µF for stability. LP38798-ADJ can operate over a wide input voltage range (3.0V to 20V), making it well-suited for many post-regulation applications. LP38798EVM evaluation board is designed to demonstrate the capabilities of the LP38798SD-ADJ. The EVM is intended to provide a flexible circuit configurations and access to points of interest.
