UM375xx 300m A, Micropower, VLDO Linear Regulator UM375xx S SOT23-5 UM375xx P SOT353 General Description The UM375xx series are VLDO (very low dropout) linear regulators designed for low power portable applications. Typical output noise is only 170μVRMS (UM37512) and maximum dropout is just 200m V at the load current of 100m A.The internal P-channel MOSFET pass transistor requires no base current, allowing the device to draw only 90μA during normal operation at the maximum load current of 300m A. Other Features include high output voltage accuracy, under voltage lockout, stability with ultra low ESR ceramic capacitors as small as 1μF, thermal overload protection and output current limiting. The UM375xx series are available in a low profile SOT23-5 and SOT353 package.
