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.
