EQUATIONS:

R1 = 0.100 V/IOUT (MAX)

R2 = (VOUT - 2.5V/1mA)

R3 = ((VIN - VBE - VSAT)*BETA(min))/IOUT (max)

UC3835/36 TYPICAL APPLICATIONS

Low Current Application

using the UC3836 internal drive transistor

Typical Output Current vs VIN and VOUT

of the UC3836 internal drive transistor

for PDISS = 0.5W (approx.)

High Current Application

using drive transistor Q2 to increase Q1 base drive

and reduce UC3836 power dissipation

Parallel Pass Transistors

can be added for high current or

high power dissipation applications
