PQ1KA213MZPH

PMIC - Voltage Regulators - Linear

The PQ1KA213MZPH is a low-dropout voltage regulator that is best suited for applications requiring low-dropout linear regulation. It features an output voltage accuracy of 0.5%, with a wide range of output voltage from 2.5V to 6V. It also has a typical power supply rejection ratio of 70dB to 90dB.

The PQ1KA213MZPH operates on an input voltage range of 3V to 15V, and is able to deliver up to 170 mA of output current. It also features thermal protection, short-circuit protection, overload protection and over-temperature protection.

Due to its low-dropout characteristics, the PQ1KA213MZPH is suitable for applications where input voltage is only slightly higher than the desired output voltage. It is especially suited to automotive, industrial and medical applications where input voltages may not always be as defined.

The PQ1KA213MZPH uses an on-chip linear regulator, based on open loop control, to regulate the output voltage. This is achieved by supplying the necessary current to the output voltage node, either from the output of the pass element or from the reference voltage, in order to maintain the desired output voltage.

In order to maintain the output voltage control loop, the PQ1KA213MZPH controls the output voltage based on an error signal, or delta, between the input and output voltages. This is achieved through a feedback loop that is built into the device.

The PQ1KA213MZPH also features a power-on reset, which helps protect the device against over-voltages and short-circuits. It further helps maintain the device’s stability, while operating at rated voltage and current.

The PQ1KA213MZPH can be used in many applications, including automotive and industrial systems, such as computer and office equipment, battery-powered systems, medical and consumer electronics and other applications where a low-dropout voltage regulator is required.

Overall, the PQ1KA213MZPH is an ideal device for applications requiring low-dropout linear regulation. It offers excellent overall performance, including good accuracy, low output voltage noise and good power supply rejection ratio. It is also cost effective, with low number of external components.
