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.

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. ________________________________________________________________________ http://www.union-ic.com Rev.02 Dec.2014 4/10 UM365xx Electrical Characteristics VCC=VOUT+1V(VOUT≥1.5V) or VCC=2.5V(VOUT≤1.5V),TA= -40℃ to +85℃.

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.
