UM175xx
300mA, Micropower, VLDO Linear Regulator UM175xx SOT23-5
General Description
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 device to draw only 100μA during normal operation at the maximum load
current of 300mA.
Other 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.
