TS6001 Rev. 1.0

For example, if VSY is 0V, then the upper input

supply voltage level for the circuit is 35V. With a

2.1k

Ω 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 resistor 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 1.5k

Ω 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.
