5 / 30 page LM3102, LM3102-Q1 www.ti.com SNVS515H – SEPTEMBER 2007 – REVISED JUNE 2015 6.5 Electrical Characteristics Specifications with standard type are for TJ = 25°C unless otherwise specified. Minimum and Maximum limits are specified 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 = 18 V, VOUT = 3.3 V. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT START-UP REGULATOR, VCC 6 over the full Operating VCC VCC output voltage CCC = 680 nF, no load V Junction Temperature 5 7.2 (TJ) range 50 over the full Operating ICC = 2mA Junction Temperature 200 (TJ) range VIN – VCC VIN – VCC dropout voltage mV 350 over the full Operating ICC = 20mA Junction Temperature 570 (TJ) range 65 over the full Operating IVCCL VCC current limit (1) VCC = 0V mA Junction Temperature 40 (TJ) range 3.75 VCC undervoltage lockout over the full Operating VCC-UVLO VIN increasing V threshold (UVLO) Junction Temperature 3.6 3.9 (TJ) range VCC-UVLO-HYS VCC UVLO hysteresis VIN decreasing – HTSSOP package 130 mV VCC-UVLO-HYS VCC UVLO hysteresis VIN decreasing – DSBGA package 150 mV tVCC-UVLO-D VCC UVLO filter delay 3 µs 0.7 over the full Operating IIN IIN operating current No switching, VFB = 1V mA Junction Temperature 1 (TJ) range 25 IIN operating current, Device over the full Operating IIN-SD VEN = 0V µA shutdown Junction Temperature 40 (TJ) range SWITCHING CHARACTERISTICS 0.18 RDS-UP-ON Main MOSFET RDS(on) Ω over the full Operating Junction Temperature (TJ) 0.375 range 0.11 RDS- DN-ON Syn.
