UM14244B
UM142xx 300mA, Low Consumption, Wide Input Voltage Linear Regulator UM142xxS SOT23-3 UM142xxY SOT89-3 UM142xxB SOT89-3 General Description The UM142xx series are a group of positive voltage output, high precise, high PSRR and low power consumption voltage regulator. The output voltages are selectable in 100mV steps within a range of 2.5V to 5V. It also can be customized on command. The UM142xx series have excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system. The UM142xx series are available in a low profile SOT23-3& SOT89-3 package, which are lead (Pb)-free. Applications Features z Reference Voltage Source z Battery Powered Equipment z Hand-Hold Equipment z Wireless LAN z GPS Receivers z Low Quiescent Current: 8μA at 5V z High PSRR: 60dB Range to 10kHz z Low Output Noise: 44μVRMS z Low Dropout: 270mV at 150mA Load z Low Temperature Coefficient: ±100ppm/°C z Excellent Line Regulation: 0.05%/V Pin.
