Hi - I need some help with this current limiting circuit - Can someone please tell me what the resistor (R4) and capacitor (c16) values need to be in order to maintain 150mA and 5v dc?

Table 1 of the datasheet shows a range of desired currents and the corresponding R(ILIM) values. A simple interpolation between two values will give you your resistor value. C16 is stated to be a 10μF, low ESR cap. You should also add a cap to VOUT per the datasheet.
