Product Description

The UM1461 series are a group of positive voltage output, high precision and low power consumption voltage regulators. The maximum input voltage is 24V. The output voltages are available in 100mV steps within a range of 2.5V to 5V. It can also be customized on request.

The UM1461 series have very low power consumption (I_Q=3.5μA) which can greatly extend battery life.

The UM1461 series are available in low profile SOT23-5 & SOT89-5 packages.
