300mA, Low Consumption, Wide Input
Voltage Linear Regulator UM142xxS SOT23-3 UM142xxY SOT89-3 UM142xxB SOT89-3
General Description
The UM142xx series are a group of positive
voltage output, high precise, high PSRR and low power consumption
voltage regulator. The output
voltages are selectable in 100mV steps within a range of 2.5V to 5V. It also can be customized on command. The UM142xx series have excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system. The UM142xx series are available in a low profile SOT23-3& SOT89-3 package, which are lead (Pb)-free.
