UM365xx
300mA, Micropower, VLDO Linear Regulator
UM365xxS
SOT23-3
UM365xxP
SOT323
General Description
The UM365xx series are VLDO (very low dropout) linear regulators designed for low power
portable applications. Maximum dropout is just 200mV at the load current of 100mA.The internal
P-channel MOSFET pass transistor requires no base current, allowing the device to draw only
90μA during normal operation at the maximum load current of 300mA.
Other features include high output voltage accuracy, under voltage lockout, stability with ultra low
ESR ceramic capacitors as small as 1μF, thermal overload protection and output current limiting.
The UM365xx series are available in a low profile SOT23-3 or SOT323 package.
Applications
Bluetooth/802.11 Cards
PDAs and Notebook Computers
Portable Instruments and
Battery-Powered Systems

Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be
impaired.
Note 2: The UM365xx is tested and specified under pulse load conditions such that T

A
. The
device is guaranteed to meet performance specifications from 0℃ to 70℃. Specifications
over the – 40℃ to 125℃ operating junction temperature range are assured by design,
characterization and correlation with statistical process controls.
Note 3: This IC includes overtemperature protection that is intended to protect the device during
momentary overload conditions. Junction temperature will exceed 125℃ when
overtemperature protection is active. Continuous operation above the specified maximum
operating junction temperature may impair device reliability.
