MIC94310-PYMT-T5

The MIC94310-PYMT-T5 is a high performance, low noise, low quiescent current, 2A micropower linear voltage regulator from Microchip. The device is housed in a three-pin SOT-223 package, and features on-chip trimming and low-dropout performance. It produces a regulated output voltage accurately and requires only two external components: a dummy resistor and a bypass capacitor.

The MIC94310-PYMT-T5 is suitable for powering DSPs, microcontrollers, and FPGAs, as well as for providing power for portable and battery-powered systems. The device has a wide input voltage range of 4.5V to 25V, and is capable of delivering up to 2A continuous output current. The MIC94310 has excellent load and line regulation and can be trimmed from 0.5V to 10V with 4-5% accuracy.

Application Field

The MIC94310-PYMT-T5 is designed for a wide range of applications, including powering DSPs, microprocessors, FPGAs and providing power for portable, battery powered systems. It is capable of supplying a stable output voltage over a wide input voltage range. The device can also be used in mobile phones, notebook computers, digital cameras, and industrial control systems.

This device is also suitable for powering thermoelectric coolers, LEDs and other low power applications. The device is also useful for automotive and panel-mounted applications because of its low quiescent current, wide input voltage range and on-chip trimming.

Working Principle

The MIC94310-PYMT-T5 operates on the principle of linear-regulating the input voltage to output a stable voltage. The device has an internal bandgap voltage reference, which is compared with the voltage at the output of the device. An error signal is generated when the difference between the output voltage and the reference voltage exceeds a certain level. This error signal is amplified and then used to drive the output stage of the device.

The MIC94310-PYMT-T5 also has a feedback resistor and a bypass capacitor, which are connected across the output terminals of the device. The feedback resistor helps to keep the output voltage stable, while the bypass capacitor provides additional stability to the output voltage. The device\'s output may be trimmed using an external resistor connected to the ADJ pin.

The MIC94310-PYMT-T5 uses the low-dropout (LDO) voltage regulating technique to maintain the output voltage steady in varying conditions. The device has a quiescent current of only 10 μA, which makes it suitable for battery-powered applications. It also offers short-circuit protection and thermal protection, as well as over-voltage protection.
