8 / 25 page  LM3253 SNVS791Q – FEBRUARY 2012 – REVISED MAY 2013 www.ti.com SYSTEM CHARACTERISTICS (continued) The following spec table entries are specified by design and verifications providing the component values in the Typical Application Circuit are used (L = 1.5 µH, DCR = 90 m Ω, TOKO DFE252010C (1269AS-H-1R5N), CIN = 10 µF, 6.3V, 0402, Samsung CL05A106MQ5NUN, COUT = 10 µF + 4.7 µF + 3 x 1.0 µF + 3300 pF: 6.3V, 0402, Samsung CL05A106MQ5NUN, CL05A475MQNRN; 6.3V, 0201 Samsung CL03A105MQ3CSN; 6.3V, 01005 Murata GRM022R60J332K). These parameters are not verified by production testing. Min and Max values are specified over the ambient temperature range TA = −30°C to 90°C. Typical values are specified at PVIN = VDD = EN = 3.8V, BP = 0V and TA = 25°C unless otherwise stated.
