Key Specifications
Product Description
The UM175xx series are VLDO (very low dropout) linear regulators designed for low power portable applications. 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.
The UM175xx series are available in a low profile SOT23-5 package.
