3 / 13 page LM123, LM323-N, LM323A www.ti.com SNVS757B – MAY 2004 – REVISED NOVEMBER 2004 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) (3) Input Voltage 20V Power Dissipation Internally Limited Operating Junction Temperature Range LM123 −55°C to +150°C LM323A −40°C to +125°C LM323-N 0°C to +125°C Storage Temperature Range −65°C to +150°C Lead Temperature (Soldering, 10 sec.) 300°C ESD Tolerance(4) 2000V (1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. (2) Refer to RETS123K drawing for LM123K military specifications. (3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (4) Human body model, 1.5 k Ω in series with 100 pF. LM123 Electrical Characteristics (1) Parameter Conditions LM123 Units Min Typ Max Output Voltage Tj = 25°C 4.7 5 5.3 V VIN = 7.5V, IOUT = 0A 7.5V ≤ VIN ≤ 15V 4.6 5.4 V 0A ≤ IOUT ≤ 3A, P ≤ 30W Line Regulation (2) Tj = 25°C 5 25 mV 7.5V ≤ VIN ≤ 15V Load Regulation (2) Tj = 25°C, VIN = 7.5V, 25 100 mV 0A ≤ IOUT ≤ 3A Quiescent Current 7.5V ≤ VIN ≤ 15V, 12 20 mA 0A ≤ IOUT ≤ 3A Output Noise Voltage Tj = 25°C 40 μVrms 10 Hz ≤ f ≤ 100 kHz Short Circuit Current Limit Tj = 25°C VIN = 15V 3 4.5 A VIN = 7.5V 4 5 A Long Term Stability 35 mV Thermal Resistance Junction to Case(3) 2 °C/W (1) Unless otherwise noted, specifications apply for −55°C ≤ Tj ≤ +150°C for the LM123, −40°C ≤ Tj ≤ +125°C for the LM323A, and 0°C ≤ Tj ≤ +125°C for the LM323-N. Although power dissipation is internally limited, specifications apply only for P ≤ 30W. (2) Load and line regulation are specified at constant junction temperature. Pulse testing is required with a pulse width ≤ 1 ms and a duty cycle ≤ 5%. (3) Without a heat sink, the thermal resistance of the TO-3 package is about 35°C/W. With a heat sink, the effective thermal resistance can only approach the specified values of 2°C/W, depending on the efficiency of the heat sink.
