Typical Applications
1.2V-25V Adjustable Regulator
Full output current not available at high input-output voltages
†C1 = 1
μF solid tantalum or 10μF aluminum electrolytic required for stability
*C2 = 1
μF solid tantalum is required only if regulator is more than 4″ from power supply filter capacitor
Regulator with Trimmable Output Voltage
Trim Procedure:
—If VOUT is −23.08V or bigger, cut out R3 (if smaller, don't cut it out).
—Then if VOUT is −22.47V or bigger, cut out R4 (if smaller, don't).
—Then if VOUT is −22.16V or bigger, cut out R5 (if smaller, don't).
This will trim the output to well within 1% of
−22.00 VDC, without any of the expense or trouble of a trim pot (see LB-
46). Of course, this technique can be used at any output voltage level.
