SPX3819M5-L-X-X(MS) Product specification SPX3819M5-L-X-X(MS) GENERAL DESCRIPTION The SPX3819M5-L-X-X(MS) series are a group of low-dropout ( LDO ) voltage regulators offering the benefits of wide input voltage range,low dropout voltage,low power consumption, and miniaturized packaging. Quiescent current of only 1.5µA makes these devices ideal for powering the battery-powered,always-on systems that require very little idle-state power dissipation to a longer service life. The SPX3819M5-L-X-X(MS) series of linear regulators are stable with the ceramic output capacitor over its wide input range from 2V to 24V and the entire range of output load current ( 0mAto 500mA ).

Current Limit Thermal Application The For continuous operation, do not exceed the absolute SPX3819M5-L-X-X(MS) series contain the curren SPX38 t limiter of output power transistor, which monitors a maximum junction temperature. The maximum power nd controls the transistor, limiting the output cur dissipation depends on the thermal resistance of the rent to 700mA ( typical ). IC package, PCB layout, rate of surrounding airflow, The output can be shorted to ground indefinitely and without damaging the part. temperature. The maximum power dissipation can be Dropout Voltage The SPX3819M5-L-X-X(MS) series use a PMOS pas s transistor to achieve low dropout. When ( VIN – VOUT ) is less than the dropout voltage ( VDROP ), t he PMOS pass device is in the linear region of operati on and the input-to-output resistance is the RDS(ON) o f the PMOS pass element. VDROP scales approximatel y with the output current because the PMOS devic difference between junction and ambient calculated as below: The max PD (Max)= (125°C − 25°C) / (200°C/W) = 0.5W . Power dissipation (PD) is equal to the product of the output current and the voltage drop across the output pass element, as shown in the equation below: PD = ( VIN – VOUT ) × IOUT e behaves as a Layout Consideration By placing input and output capacitors on the same side of the PCB as the LDO, and placing them as close as is practical to the package can achieve the best performance. The ground connections for input and output capacitors must be back to the SPX3819M5-L-X-X(MS) ground pin using as wide and as short of a copper trace as is practical. Connections using long trace lengths, narrow trace widths, and/or connections through via must be avoided. These add parasitic inductances and resistance that results in worse performance especially during transient conditions.
