Maximum of 32 mV at IO = 100 mA (TPS7150) D Very Low Quiescent Current – Independent of Load . . . 285 µA Typ D Extremely Low Sleep-State Current 0.5 µA Max D 2% Tolerance Over Specified Conditions For Fixed-Output Versions D Output Current Range of 0 mA to 500 mA D TSSOP Package Option Offers Reduced Component Height for Space-Critical Applications D Power-Good (PG) Status Output description The TPS71xx integrated circuits are a family of micropower low-dropout (LDO) voltage regulators. An order of magnitude reduction in dropout voltage and quiescent current over conventional LDO performance is achieved by replacing the typical pnp pass transistor with a PMOS device.
