The maximum allowable power dissipation is a function of the maximum junction temperature TJ (MAX), the junction-to-ambient thermal resistance θJA, and the ambient temperature TA. The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD (MAX) = (TJ (MAX)TA)/θJA. Exceeding the maximum allowable power dissipation produces an excessive die temperature, causing the regulator to go into thermal shutdown.

All Rights Reserved. 11 MPQ2019 - 40V, 300mA, LOW QUIESCENT CURRENT LINEAR REGULATOR OPERATION The MPQ2019 is a linear regulator that supplies power to systems with high-voltage batteries. It includes a wide 3V to 40V input range, lowdropout voltage, and a low-quiescent supply current (see Figure 1). The MPQ2019 provides a wide variety of fixed output-voltage options: 1.8V, 1.9V, 2.3V, 2.5V, 3.0V, 3.3V, 3.45V, and 5.0V; Also, it provides the output-adjustable option (from 1.2V to 15V). The regulator output current is limited internally, and the device is protected against short-circuit, over-load, and over-temperature conditions (see Figure 2). The peak-output current is limited to around 1000mA, which exceeds the 300mA recommended continuous-output current. When the junction temperature is too high, the thermal sensor sends a signal to the control logic that shuts down the IC. The IC will re-start when the temperature has sufficiently cooled. The output-adjustable version has an output that is adjustable from 1.2V to 15V with a simple resistor divider. It uses external feedback, allowing the user to set the output voltage with an external resistor divider. The FB threshold is 1.25V, typically. The maximum power-output current is a function of the package’s maximum power dissipation for a given temperature. The maximum power dissipation is dependent on the thermal resistance of the case and the circuit board, the temperature difference between the die junction and the ambient air, and the rate of air flow. GND and the exposed pad must be connected to the ground plane for proper dissipation. The IC enters shutdown mode when EN is low. In shutdown mode, the pass transistor, control circuitry, reference, and all biases turn off; this reduces the supply current to <0.1µA. Connect EN to IN for automatic start-up.

OUT MPQ2019 GND R1 FB R2 Choose R2=1MΩ to maintain a 1.215µA minimum load. Calculate the value for R1 using the following equation: V R1 = R2 × OUT − 1 1.25V For a fixed-output version, VOUT can also be adjusted by adding an external resistor divider. When choosing an external divider, just note to take the internal FB resistor divider into consideration. OUT VOUT R1_IN R2_IN GND R1 FB R2 Figure 4. FB Divider for Fixed-Output Version When R2 is selected, R1 can be calculated by below equation: R1 = R1_ IN 1.25 × R1_ IN × (R2 + R2 _ IN) −1 ( VOUT − 1.25 ) × R2 × R2 _ IN The internal FB resistor dividers for different fixed- output versions are shown in below Table.

When EN is pulled above 1.8V, the chip starts up. If this function is not used, EN can be connected to Vin directly. Input Capacitor For efficient operation, place a ceramic capacitor (C1) between 1µF and 10µF of dielectric type (X5R or X7R) between the input pin and ground. Larger values in this range improve line transient response. Output Capacitor For stable operation, use a ceramic capacitor (C2) of type X5R or X7R between 1µF and 22µF. Larger values in this range improve load transient response and reduce noise. Output capacitors of other dielectric types may be used, but they are not recommended as their capacitance can deviate greatly from their rated value over temperature. To improve load transient response, add a small ceramic (X5R, X7R, or Y5V dielectric) 2.2nF feed-forward capacitor in parallel with R1. The feed-forward capacitor is not required for stable operation. Output Noise The MPQ2019 exhibits noise on the output during normal operation. This noise is negligible for most applications. However, in applications that include analog-to-digital converters (ADCs) of more than 12 bits, consider the ADC’s power supply rejection specifications. The feed-forward capacitor C2 across R1 reduces significantly the output noise. MPQ2019 Rev. 1.1 www.MonolithicPower.com 5/24/2016 MPS Proprietary Information. Patent Protected.

It is recommended highly to duplicate the EVB layout for optimum performance. If changes are necessary, refer to Figure 5 and follow the guidelines below: 1) Place input and output bypass ceramic capacitors close to IN and OUT, respectively. 2) Ensure all feedback connections are short and direct. Place the feedback resistors and compensation components as close to the chip as possible. 3) Connect IN, OUT, and especially, GND, respectively, to a large copper area to cool the chip. This improves thermal performance and long-term reliability.
