RP123x LDO Voltage Regulators

Nisshinbo RP123x LDO Voltage Regulators provide low output noise, high ripple rejection, and fast response characteristics achieved by low supply current. These voltage regulators save space by adopting a 4-pin small package without a noise bypass capacitor. The RP123x voltage regulators deliver long-duration of operation for battery-powered equipment by low supply current. These voltage regulators operate at 9.5µA supply current and 8μVrms output noise.
