Description
UM375xx 300mA, Micropower, VLDO Linear Regulator UM375xxS SOT23-5 UM375xxP SOT353 General Description The UM375xx series are VLDO (very low dropout) linear regulators designed for low power portable applications. Typical output noise is only 170μVRMS (UM37512) and 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 UM375xx series are available in a low profile SOT23-5 and SOT353 package. Applications z Bluetooth/802.11 Cards z PDAs and Notebook Computers z Portable Instruments and Battery-Powered Systems z Cellular Phones Features z Input Voltage Range: 2.0V to 6.0V z Very Low Dropout: 200mV (Max) at 100mA z Low Noise:170μVRMS (UM37512,10Hz to 100kHz) z ±2% Voltage Accuracy at 150mA z Fixed Output Voltage: 1.2V to 5.0V with 100mV Interval z Output Current Limit z Stable with 1μF Output Capacitor z Thermal Overload Protection z Low Profile SOT23-5 and SOT353 Packages Pin Configurations Top View M: Month Code UM375xxS SOT23-5 ________________________________________________________________________ http://www.union-ic.com Rev.07 Aug.2016 1/12 UM375xx Pin Description M: Month Code UM375xxP SOT...
