LP38798 800-mA Ultra-Low-Noise, High-PSRR LDO
The LP38798-ADJ is a high-performance, low-noise LDO that can supply up to 800 mA output current. Designed to meet the requirements of sensitive RF/Analog circuitry, the 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. The LP38798SD-ADJ is stable with both ceramic and tantalum output capacitors and requires a minimum output capacitance of only 1 µF for stability. The LP38798-ADJ can operate over a wide input voltage range (3 V to 20 V) making it well suited for many post-regulation applications.
