Ultra-Low Noise, High PSRR LDO LP38798 is Ideal for RF/Analog Circuits

This post sponsored by Texas Instruments.

The LP38798-ADJ is a high-performance linear regulator capable of supplying 800 mA output current.

It is 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 (5 µVRMS) and high PSRR (90 dB at 10 kHz, 60 dB at 100 kHz) at switching power supply frequencies.

It 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), which makes it well-suited for many post-regulation applications. It features excellent line and load transient response, as well as current limit and over-temperature protection. Applications for the LP38798-ADJ include RF and VCO power, wireless LAN devices, wireless cable modems, and low noise post-regulation.
