ADP7158ACPZ-1.8-R7 | 1.8 V Ultra-Low Noise LDO Regulator | High PSRR Power IC

Product Overview

     The ADP7158ACPZ-1.8-R7 is a high performance low dropout (LDO) linear regulator that provides a fixed 1.8 V output with ultra-low noise and excellent power-supply rejection ratio (PSRR). Designed for noise-sensitive systems, this device supports high-precision analog circuitry, RF front ends, data converters, and digital logic supplies. With low quiescent current and fast transient response, it ensures a stable power rail for both analog and digital domains. Stable operation with small ceramic capacitors reduces BOM and simplifies system design.
