The MIC39301-1.65BU TR is a high-accuracy, low-dropout voltage regulator. It operates over a wide input voltage range of 1.6V to 4.8V and provides a highly regulated output voltage of 1.65V with a maximum temperature coefficient of ±150 ppm/°C. It has a very high peak current capability of up to 4.7A and a typical quiescent current of 195 μA, making it an ideal choice for battery powered devices that require a tightly regulated power supply.

The MIC39301-1.65BU TR is an adjustable, linear regulator with an external reference voltage. The device is designed with a fixed internal upper reference voltage of 1.65V and the end user can adjust the output voltage and point sets the lower reference voltage of 1.592V. The device provides a high accuracy, low noise and low dropout output voltage that is well suited for applications such as embedded systems, electronic point of sale and server infrarose applications.

The MIC39301-1.65BU TR is designed to ensure a stable power supply during sudden changes in input voltage as well as sudden changes in load current. It has an advanced output regulation stage with a high power PSRR (power supply rejection ratio). This enables the device to maintain stable output voltage even when the input voltage fluctuates. The high PSRR also helps reduce the switching noise from the power stage. The device also features an active current limit feature that limits the inrush current during startup, which helps protect the device from over-current damage.

The MIC39301-1.65BU TR uses a Voltage Regulating Element (VRE) that is connected to the external reference voltage. The VRE, along with the error amplifier, is used to regulate the output voltage. The error amplifier compares the actual output voltage with the reference voltage to determine the necessary correction voltage. The correction voltage is then output as an error signal and sent to the VRE, which reduces the amount of current flowing from the input to the output, thus resulting in a maintain output voltage.

The MIC39301-1.65BU TR is designed to meet the most exacting requirements of industrial and embedded applications. The low quiescent current of 195 μA and the high power PSRR of the device make it an ideal choice for battery powered applications. It is also suitable for powering a wide range of loads, including high capacitance that require a stable and accurate output voltage. The device also features an internal thermal shutdown that prevents the device from over-heating, and an over-current protection circuit that helps prevent short circuits.

The MIC39301-1.65BU TR Voltage Regulating Element is a linear regulator ideal for applications that require precise control regimes with minimal power dissipation. This device is designed with an adjustable, external reference voltage for accurate control of the output voltage and point sets the lower reference voltage of 1.592V. This feature, along with its high current capability, low quiescent current, and excellent noise and PSRR performance, make it an ideal choice for demanding applications such as industrial and embedded systems, electronic point of sale, and server infrarose applications.
