General Description
The UM1550/1560 series is a set of high input voltage low quiescent current regulator
implemented in CMOS technology. They can deliver 250mA output current and allow an input
voltage as high as 8V. They are available with several fixed output voltages ranging from 1.2V to
5.0V. CMOS technology ensures low voltage drop and low quiescent current.
The UM1550 is available in SOT23-3, SOT89-3, DFN6 2.0×2.0 and DFN4 1.0×1.0 packages. The
UM1560 is available in SOT23-5, DFN6 2.0×2.0 and DFN4 1.0×1.0 packages.

Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be
impaired.
Note 2: The UM1550/1560 is tested and specified under pulse load conditions such that TJ≈TA.
Specifications over the – 40°C to 125°C operating junction temperature range are assured by
design, characterization and correlation with statistical process controls.
Note 3: This IC includes over temperature protection that is intended to protect the device during
momentary overload conditions. Junction temperature will exceed 125°C when over
temperature protection is active. Continuous operation above the specified maximum
operating junction temperature may impair device reliability.
Note 4: The maximum allowable power dissipation of any TA (ambient temperature) is PDMAX=
(TJMAX-TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive
die temperature and the regulator will go into thermal shutdown.
