5 / 24 page LMZ12003 www.ti.com SNVS636M – DECEMBER 2009 – REVISED MARCH 2013 Electrical Characteristics (continued) Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the junction temperature (TJ) range of -40°C to +125°C. Minimum and Maximum limits are ensured through test, design or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated the following conditions apply: VIN = 12V, Vout = 1.8V (1) Min Typ Max Symbol Parameter Conditions Units (2) (3) (2) IFB Feedback input bias current 5 nA IQ Non Switching Input Current VFB= 0.86V 1 mA ISD Shut Down Quiescent Current VEN= 0V 25 μA Thermal Characteristics TSD Thermal Shutdown Rising 165 °C TSD-HYST Thermal shutdown hysteresis Falling 15 °C θJA (4) Junction to Ambient 4 layer JEDEC Printed Circuit Board, 19.3 °C/W 100 vias, No air flow 2 layer JEDEC Printed Circuit Board, No 21.5 °C/W air flow θJC Junction to Case No air flow 1.9 °C/W PERFORMANCE PARAMETERS ΔVO Output Voltage Ripple 8 mV PP ΔVO/ΔVIN Line Regulation VIN = 8V to 20V, IO= 3A .01 % ΔVO/ΔVIN Load Regulation VIN = 12V 1.5 mV/A η Efficiency VIN = 12V VO = 1.8V IO = 1A 87 % η Efficiency VIN = 12V VO = 1.8V IO = 3A 77 % (4) θJA measured on a 1.705” x 3.0” four layer board, with one ounce copper, thirty five 12 mil thermal vias, no air flow, and 1W power dissipation.
