10 / 12 page  TS6001 Page 10 TS6001DS r1p0 RTFDS For example, if VSY is 0V, then the upper input supply voltage level for the circuit is 35V. With a 2.1kΩ load and the TS6001’s supply current of 35µA (max), this circuit supplies approximately a 1.23-mA current to the load. In many current source applications, the possibility of an output short-circuit condition - whether transient or sustained - exists. It is recommended to test thoroughly for either scenario to prevent the possibility that the TS6001 would be exposed to a total voltage from its IN terminal to GND terminal higher than its absolute maximum rating of 13.5V. Boosting the TS6001’s Output Current Drive While the TS6001 is capable of sourcing up to 500µA with excellent load regulation, there are applications where tight load regulation is required at much higher output load currents. By adding a general-purpose, industry-standard PNP transistor and one re sistor to the TS6001’s basic configuration as shown in Figure 7, increasing a precision reference’s output source current drive is straightforward. Using a 2N2905 PNP transistor and a 1.5kΩ resistor, the TS6001 is able to maintain excellent load regulation while sourcing load currents up to 150mA. If the application circuit is designed to operate across a wide temperature range, it is recommended that circuit performance is thoroughly evaluated across the PNP transistor’s beta ( β, or current gain) distribution. When the PNP transistor’s current gain is a minimum, the increase in base current must be absorbed by the TS6001 for a given load current. For higher output load currents, higher output power PNP transistors can be used so long as good thermal management techniques are applied and transistor current-gain vs ambient temperature behavior is evaluated.
