UM17528, UM17533 Datasheet (Union Semiconductor)

UM17528, UM17533, VLDO Linear Regulator

The UM175xx series are VLDO (very low dropout) linear regulators designed for low power portable applications.

Typical output noise is only 75μVRMS and maximum dropout is just 90mV at the load current of 150mA.The internal P-channel MOSFET pass transistor requires no base current, allowing the devi

UM17528 Features

* include high output voltage accuracy, excellent transient response, under voltage lockout, stability with ultralow ESR ceramic capacitors as small as 1μF, reverse-battery protection, short-circuit and thermal overload protection and output current limiting. The UM175xx series are available in a low
