Changes in output voltage due to thermal effects are covered separately by the thermal regulation specification. (2) Dropout is defined as the input to output differential at which the output drops 2% below its nominal value measured at 1-V differential. (3) For stability across the input voltage and temperature. For ADJ versions, the minimum current can be set by R1 and R2. (4) Thermal regulation is defined as the change in output voltage at a specified time after a change in power dissipation is applied, excluding line and load regulation effects. (5) CBYP is optional and connected to the BYP/ADJ pin. 6 Submit Documentation Feedback |
