5.5 Electrical Characteristics

V_IN = V_OUT(NOM) + 1V or 4V (whichever is greater for either fixed or adjustable versions), I_LOAD = 1mA, V_EN = 3V, and C_OUT = C_IN = 2.2μF (unless otherwise noted); for the TPS79801, the FB pin is tied to V_OUT; typical values are at T_J = 25°C

(1) Full range T_J = –40°C to 125°C.

(2) This parameter is tested and specified under pulse load conditions such that T_J = T_A. This device is 100% production tested at T_A = 25°C. Performance at full range is specified by design, characterization, bench to ATE correlation testing, and other statistical process controls.

(4) This device is limited by a maximum junction temperature of T_J = 125°C. The regulated output voltage specification cannot be applied to all combinations of various V_IN, V_OUT, ambient temperature, and I_OUT conditions. When operating with large voltage differentials across the device, the output load must be limited so as not to violate the maximum junction temperature for a given ambient temperature.

(5) In the adjustable version test, the output uses an external voltage divider. This resistor voltage divider is made up of R₁ = 215k? and R2 (bottom resistor) = 340k?. This configuration preloads the output with 6μA.

(6) By definition, dropout voltage is the minimum input voltage needed to maintain a given output voltage at a specific load current. For dropout testing, minimum V_IN = V_OUT(NOM) × 0.96. This specification ensures that the device is in dropout and takes into account the output voltage tolerance over the full temperature range.

(7) Ground pin current is tested with V_IN = V_OUT(NOM) or 3V, whichever is greater.

(8) FB pin current flows into the FB pin.

(9) EN pin current flows into the EN pin.

(10) Current limit is tested with V_IN = V_OUT(NOM) + 0.5V or 3V, whichever is greater. V_OUT is forced to V_OUT(NOM) – 0.1V and the output current is measured.

(11) Reverse output current is tested with the IN pin tied to ground and the output forced to V_OUT(NOM) +0.1V. This current flows into the OUT pin and out of the GND pin and then measured.

(12) Specified by design.
