RP120 Series

Low Input / Output 1.5 A LDO Regulator

The RP120 is a very low dropout regulator which operates from input voltage as low as 0.768 V (@VSET = 0.6 V, VBIAS = 3.3 V, IOUT = 1.5 A). The LDO uses an internal low on-resistance (67 mΩ @VSET = 0.6 V, VBIAS = 3.3 V, IOUT = 1 A) NMOS transistor as the driver. The VBIAS pin provides the higher supply necessary for the LDO circuitry while the output current comes directly from the VIN input for high efficiency regulation.
