The LP38788-ADJ is a high performance linear regulator capable of supplying 800 mA output current. Designed to meet the requirements of sensitive RF/Analog circuitry, the LP38788 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 LP38788-ADJ is stable with both ceramic and tantalum output capacitors and requires a minimum output capacitor of only 1 µF for stability.

The LP38788-ADJ can operate over a wide input voltage range (4.5V to 15V) making it well suited for many post regulation applications.

Available in a 12-Lead LLP package (4.0 x 4.0 x 0.8 mm).
