Wide Vin/Vout Low Dropout (LDO) Regulators

onsemi Wide V_IN/V_OUT Low Dropout (LDO) Regulators offer ultra-low quiescent current, fast transient response, and high input and output voltage ranges. Additional features, such as high Power Supply Rejection Ratio (PSRR) and low-noise are also available as options. These devices are designed to meet a variety of applications, such as Wi-Fi® connectivity, automotive, multi-battery powered equipment, and industrial motor control.
