Note 2: The UM365xx is tested and specified under pul se load conditions such that T J≈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 prot ect the device during momentary overload conditions. Junct ion 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 7/10 UM365xx Typical Performance Characteristics (Continued) Line Transient Response Load Transie nt Response Pin Function GND (Pin 1): Ground and Heat Sink. Solder to a ground plane or large pad to maximize heat dissipation. OUT (Pin 2): V oltage 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 throu gh 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. Typical Application Circuit UM365xx VIN VOUT GND IN OUT 1μF 1μF IOUT=10mA to 150mA VOUT=3.3V(100mV/div) VIN=4.3V, 100us/div Vin=4.0V to 5.0V VOUT=3.3V (50mV/div) Iload=150mA, 50us/div
