一,产品概述(General Description) ![]() The JTMH2002 series are highly accurate, Dual low noise, CMOS LDO voltage regulators.Performance features of the series include low output noise, high ripple rejection ratio, low dropout and very fast turn-on times. The output voltage for each regulator is set independently by laser trimming. The JTMH2002 series is also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies. The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. The JTMH2002 series is available in the TSOT23-6L or SOT23-6L packages(or upon request). 二.产品特点(Features) ![]() Maximum Output Current : More than 150mA (300mA limit) Dropout Voltage : 100mV @100mA OUT1 Voltage: 2.8V OUT2 Voltage: 1.8V Operating Voltage Range : 2.9V ~ 5.5V Low Power Consumption :180μA (TYP.)
