GaAs (-2.0V) ICs from an existing +5.0V or +3.3V source. These regulators are similar to the popular PT6900 series with the added feature of Power T rends’ unique solderable copper case. A 330µF electrolytic capacitor is required on both the input and output for proper operation. Also n ote that this product does not include short- circuit protection.

T able 1 gives the allowable adjustment range for each model in the series as V a (min) and Va (max). Adjust Up: An increase in the output voltage is obtained by adding a resistor R2, between pin 2 (Vo adjust) and pin 8 (Remote Sense GND). Adjust Down: Add a resistor (R1), between pin 2 (Vo ad- just) and pin 22 (Remote Sense Vo). Refer to Figure 1 and T able 2 for both the placement and value of the required resistor, either (R1) or R2 as appropriate. Notes: 1. Only a single 1% resistor is required in either the (R1) or R2 location. Do not use (R1) and R2 simultaneously. Place the resistor as close to the ISR as possible. 2. Never connect capacitors from Vo adjust to either GND, Vout, or the Sense pins. Any capacitance added to the Vo adjust pin will affect the stability of the ISR. 3. If the sense pins are not being used, the resistors (R1) and R2 can be connected to Vout and GND respectively. 4. An increase in the output voltage must be accompanied by a corresponding reduction in the maximum output current. The revised maximum output current must be reduced to the equivalent of 12Watts. i.e. Iout (max) = 12 Adc,Va where Va is the adjusted output voltage. Figure 1 The respective values of (R1) [adjust down], and R2 [ad- just up], can also be calculated using the following formulas. (R1) = 24.9 (Va – Vr) – Rs kΩ (Vo – Va) R2 = 24.9 Vr – Rs kΩ (Va – Vo) Where: Vo = Original output voltage Va = Adjusted output voltage Vr = Reference voltage in T able 1 Rs = The resistance given in T able 1 T able1 PT6900/PT6910 ADJUSTMENT RANGE AND FORMULA PARAMETERS Series Pt # 5.0V Bus PT 6903/13 PT6901/11 PT6902/12 3.3V Bus PT 6904/14 PT6905/15 Vo (nom) -1.5V -2.0V -5.2V Va (min) -1.2V -1.4V -2.7V Va (max) -3.4V -4.5V -6.5V Rs (kΩΩΩΩΩ ) 12.7 10.0 17.4 C in C out+ (Up) (R1) (Down) COMCOM Vout(-)+Vin PT6900/10 16 - 21 29 - 15 3 - 7 +Vin -Vo GND Vo(adj) Vo(sense) GND(sense) L O A D
