UM165xx 300mA, Micropower, VLDO Linear Regulator UM165xx SOT23-3 General Description The UM165xx series are VLDO (very low dropout) linear regulators designed for low power portable applications. Typical output noise is only 75μVRMS and maximum dropout is just 90mV at the load current of 150mA.The internal P-channel MOSFET pass transistor requires no base current, allowing the device to draw only 100μA during normal operation at the maximum load current of 300mA. Other features include high output voltage accuracy, excellent transient response, under voltage lockout, stability with ultralow ESR ceramic capacitors as small as 1μF, reverse-battery protection, short-circuit and thermal overload protection and output current limiting. The UM165xx series are available in a low profile SOT23-3 package.

Note 2: The UM165xx 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.05 Nov.2014 2/7 UM165xx Electrical Characteristics Symbol Parameter VIN Input Voltage Range VUVLO1 Input Under Voltage Lockout Input Under Voltage Lockout （Note1） VUVLO2 （Note2） IQ IOUT VIN falling 2.1 2.3 V Human Body Mode Output Current Load Regulation Output Voltage Noise Power Supply Ripple Rejection V V ESD Rating Line Regulation 6.0 2.6 100 Output Current Limit Input Reverse Leakage Current (OUT to IN Leakage Current) Thermal-Shutdown Temperature Thermal-Shutdown Hysteresis Unit 2.0 IOUT=300mA ILIMT Max VIN falling 90 Dropout Voltage PSRR Typ IOUT=0mA ΔVDO ΔTSHDN Min VOUT+ VDROP Operating Quiescent Current Output Voltage Accuracy TSHDN Test Conditions 1mA≤IOUT≤150mA, TA=+25℃ 1mA≤IOUT≤150mA, TA=-40℃ to +85℃ 1mA≤IOUT≤300mA, TA=-40℃ to +85℃ IOUT=150mA VIN≥2.5V 2 kV 300 mA -1 +1 -2 +2 -2.5 +2.5 90 450 VIN=4V, VOUT=5.5V chip active VOUT+1V≤VIN≤VOUT+2V IOUT=10mA VIN=VOUT+1V 1mA≤IOUT≤150mA 10Hz to 100KHz CIN=0.1μF, IOUT=10mA f=100Hz VIN=VOUT+1V IOUT=100mA μA % mV mA 0.01 1.5 μA 160 ℃ 20 ℃ 0.09 %/V 0.2 % 75 μVRMS 70 f=1kHz 65 f=10kHz 50 f=100kHz 40 dB Note1: VUVLO1 is measured for devices with VOUT≥1.8V.

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. See the Applications Information section for more information on output capacitance. IN (Pin 3): Power for UM165xx and Load. Power is supplied to the devices through the IN pin. The IN pin should be locally bypassed to ground if the UM165xx 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. The UM165xx series are designed to withstand reverse voltages on the IN pin with respect to both ground and the output pin. In the case of a reversed input, which can happen if a battery is plugged in backwards, the UM165xx will act as if there is a large resistor in series with its input with only a small amount of current flow.
