Electrical specifications do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(max) , the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD(max) = (TJ(max) – TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. ◈ Guaranteed Operating Conditions ( Ta = 25℃ ) Parameter Symbol Limits Unit Supply Input Voltage VIN Vo+0.5~20 V Enable Input Voltage VCTL 0~ VIN V Output Current IOUT 0~ 1.0 A KSD-I0T009-002 Jan. 2011 REV. 02 3 S52Dxxx ◈ Electrical characteristics ( VIN=VOUT+1.0V, CIN = 0.33uF, COUT = 47 uF, IOUT = 5mA, TJ=25℃ ; unless noted ) NO 1 Characteristics Output Voltage Symbol Specification Condition Unit MIN.
