The external resistor divider adds a 300-µA DC load on the output. (8) GND pin current is tested with VIN = 2.9 V and a current source load. The GND pin current decreases at higher input voltages. (9) Parameter is specified by bench characterization and is not tested in production. (10) ADJ pin bias current flows into the ADJ pin. (11) This maximum limit applies to SMD 5962R1222403VXC post 100kRads (Si) test at 25°C. (12) Parameter is specified by characterization for KGD and is not tested in production. (13) Reverse output current is tested with the IN pin grounded and the OUT pin forced to the rated output voltage. This current flows into the OUT pin and out the GND pin. 8 Submit Documentation Feedback Copyright © 2013–2015, Texas Instruments Incorporated |
