... The current limit is fixed at 2.5A to control the cur- rent in short circuit condition within ±8%. The cur- rent is sensed in the power mos in order to limit the power dissipation. The device is also provided of a thermal shut down that limits the internal temperature at 150°C with an histeresys of 20° ...

... Regulated output voltage. This pin is connected to the source of the internal N-mos. Connect this pin to a capacitor of 10 µ – PGOOD Power good output. The pin is open drain and detects the output voltage forced low if the output voltage is lower than 90% of the programmed voltage GND Ground pin ...

... Input Capacitor The input capacitor value depends on a lot of factors such as load transient requirements, input source (battery or DC/DC converter) and its distance from the input cap. Usually a 47µF is enough for any application but a much lower value can be sufficient in many cases. Output Capacitor The output capacitor choice depends basically on the load transient requirements ...

... So, using very low ESR ceramic capacitors could produce oscillations at the output, in particular when regulating high output voltages (adjustable version). To solve this issue is sufficient to add a small capacitor (e.g. 1nF to 10nF) in parallel to the high side resistor of the external divider, as shown in figure 9. Figure 9. Compensation Network ...

... This means that the device is able to deliver a DC output current of 2A only with a very low dropout. In many applications, high output current pulses are required. If their duration is shorter than the thermal con- stant time of the board, the thermal impedance (not the thermal resistance) has to be considered ...
