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, short-circuit and thermal
overload protection and output current limiting.
The UM175XX series are available in a low profile SOT23-5 package.
