(2) Thermal resistance value RθJA is based on the EIA/JEDEC High-K printed circuit board defined by: JESD51-7 - High Effective Thermal Conductivity Test Board for Leaded Surface Mount Packages. 6.4 Thermal Information THERMAL METRIC(1) LP2982 UNIT DBV (SOT-23) 5 PINS RθJA Junction-to-ambient thermal resistance, High-K(2) 175.7 °C/W RθJC(top) Junction-to-case (top) thermal resistance 121.8 °C/W RθJB Junction-to-board thermal resistance 29.5 °C/W ψJT Junction-to-top characterization parameter 16.1 °C/W ψJB Junction-to-board characterization parameter 29.0 °C/W (1) Temperature range are ensured through correlation using statistical quality control (SQC) methods. The limits are used to calculate average outgoing quality level (AOQL). (2) Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below the value measured with a 1-V differential. 6.5 Electrical Characteristics Unless otherwise specified: TJ = 25°C, VIN = VO(NOM) + 1 V, IL = 1 mA, COUT = 1 μF, VON/OFF = 2 V.
