2 / 13 page LM7905, LM7912, LM7915 SNOSBQ7C – JUNE 1999 – REVISED MAY 2013 www.ti.com 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) Input Voltage (Vo = −5V) −25V (Vo = −12V and −15V) −35V Input-Output Differential (Vo = −5V) 25V (Vo = −12V and −15V) 30V Power Dissipation (2) Internally Limited Operating Junction Temperature Range 0°C to +125°C Storage Temperature Range −65°C to +150°C Lead Temperature (Soldering, 10 sec.) 230°C (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not ensure Specific Performance limits. For ensured specifications and test conditions, see the Electrical Characteristics. (2) Refer to DESIGN CONSIDERATIONS for details. ELECTRICAL CHARACTERISTICS Conditions unless otherwise noted: IOUT = 500mA, CIN = 2.2μF, COUT = 1μF, 0°C ≤ TJ ≤ +125°C, Power Dissipation ≤ 1.5W.
