4 / 32 page LP2950, LP2951 SLVS582I – APRIL 2006 – REVISED NOVEMBER 2014 www.ti.com 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VIN Continuous input voltage range –0.3 30 V VSHDN SHUTDOWN input voltage range –1.5 30 V VERROR ERROR comparator output voltage range(2) –1.5 30 V VFDBK FEEDBACK input voltage range (2) (3) –1.5 30 V (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) May exceed input supply voltage (3) If load is returned to a negative power supply, the output must be diode clamped to GND. 6.2 Handling Ratings MIN MAX UNIT Tstg Storage temperature range –65 150 °C Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all 0 2500 pins(1) V(ESD) Electrostatic discharge V Charged device model (CDM), per JEDEC specification 0 1000 JESD22-C101, all pins(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions MIN MAX UNIT VIN Supply input voltage See (1) 30 V TJ Operating virtual junction temperature –40 125 °C (1) Minimum VIN is the greater of: (a) 2 V (25°C), 2.3 V (over temperature), or (b) VOUT(MAX) + Dropout (Max) at rated IL 6.4 Thermal Information LP2950 LP2951 THERMAL METRIC(1) LP D P DRG UNIT 3 PINS 8 PINS RθJA Junction-to-ambient thermal resistance 140 97 84.6 52.44 °C/W (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report (SPRA953). 4 Submit Documentation Feedback Copyright © 2006–2014, Texas Instruments Incorporated Product Folder Links: LP2950 LP2951 |
