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.

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 TJ≈TA. 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.

Pin Function
GND (Pin 1): Ground and Heat Sink. Solder to a ground plane or large pad to maximize heat
dissipation.
OUT (Pin 2): Voltage Regulated Output. The OUT pin supplies power to the load. A minimum
output capacitor of 1μF is required to ensure stability. Larger output capacitors may be required
for applications with large transient loads to limit peak voltage transients.
IN (Pin 3): Power for UM365xx and Load Power is supplied to the devices through the IN pin.
The IN pin should be locally bypassed to ground if the UM365xx series are more than a few
inches away from another source of bulk capacitance. In general, the output impedance of a
battery rises with frequency, so it is usually advisable to include an input bypass capacitor in
battery-powered circuits. A capacitor in the range of 0.1μF to 1μF is usually sufficient.
