3 / 24 page LP2980-N www.ti.com SNOS733M – APRIL 2000 – REVISED JUNE 2013 ABSOLUTE MAXIMUM RATINGS (1) (2) Storage Temperature Range −65°C to +150°C Operating Junction Temperature Range −40°C to +125°C Lead Temperature (Soldering, 5 sec.) 260°C ESD Rating(3) 2 kV Power Dissipation(4) Internally Limited Input Supply Voltage (Survival) −0.3V to +16V Input Supply Voltage (Operating) 2.1V to +16V Shutdown Input Voltage (Survival) −0.3V to +16V Output Voltage (Survival)(5) −0.3V to +9V IOUT (Survival) Short Circuit Protected Input-Output Voltage (Survival)(6) −0.3V to +16V (1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the device outside of its rated operating conditions. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) The ESD rating of pins 3 and 4 for the SOT-23 package is 1 kV. (4) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: The value of θJA for the SOT-23 package is 220°C/W. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. (5) If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2980-N output must be diode-clamped to ground. (6) The output PNP structure contains a diode between the VIN and VOUT terminals that is normally reverse-biased. Reversing the polarity from VIN to VOUT will turn on this diode (See REVERSE CURRENT PATH). ELECTRICAL CHARACTERISTICS Limits in standard typeface are for TJ = 25°C, and limits in boldface type apply over the full operating temperature range. Unless otherwise specified: VIN = VO(NOM) + 1V, IL = 1 mA, COUT = 1 μF, VON/OFF = 2V.

Limits over the operating 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 1V differential.
