Analog Devices Inc. LTM®4709 µModule Linear Regulators
Analog Devices Inc. LTM®4709 µModule Linear Regulators are versatile low-voltage triple 3A µModule linear regulators. Analog Devices Inc. LTM4709 offers high power supply rejection, minimal noise, and rapid transient response. This regulator integrates low dropout linear regulators (LDO), capacitors, and resistors. The devices operate within an input voltage range of 0.6V to 5.5V and support an output voltage range of 0.5V to 4.2V for three 3A channels. The regulators have a typical dropout voltage of 45mV. Configure the output voltage digitally in increments of 50mV from 0.5V to 1.2V, 100mV increments from 1.2V to 1.8V, and discrete levels at 2V, 2.5V, 3V, 3.3V, and 4.2V.
