Positive High Voltage High Current Regulator:
Positive High Voltage High Current Regulator – For this type, output voltage from +7V to +37V and load current IL > 150 mA. For this a external transistor Q1 is connected, as shown in the Fig. 2.115.
For this different expressions are similar to basic high voltage regulator and reproduced for the convenience.
While the power dissipation of transistor Q1 and the IC is given by the same expressions as given by the equations (5) and (6).
