UM3730 150mA, Micropower, Low Dropout Linear Regulator UM3730DA-xx DFN4 1.0×1.0 UM3730P-xx SOT353 General Description The UM3730 series are low dropout linear regulators designed for low power portable applications. Typical output noise is only 220μVRMS and typical dropout voltage is 155mV at the load current of 150mA. Ideal for battery powered applications, the UM3730 draws only 29μA current during no load operation. The UM3730 includes an auto-discharge feature that is activated when the enable pin is low. Other features include 2% output voltage accuracy, excellent transient response, stability with ultra low ESR ceramic capacitors as small as 1μF, thermal overload protection and output current limiting. The UM3730 series are available in low profile DFN4 1.0×1.0 and SOT353 packages.

Note 2: The UM3730 is tested and specified under pulse load conditions such that TJ≈TA. 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 over temperature protection that is intended to protect the device during momentary overload conditions. 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. ________________________________________________________________________ http://www.union-ic.com Rev.02 Dec.2014 4/11 UM3730 Electrical Characteristics VIN=VEN=VOUT+1V, CIN=COUT=1μF, TA=25℃.
