Parameter Conditions Min Typ Max Unit Reference Voltage VIN = 2.75, Io= 1A 1.225 1.25 1.275 V VIN = 3V ~ 12V, Io= 1A 1.470 1.5 1.530 V VIN = 3.3V ~ 12V, Io= 1A 1.764 1.8 1.836 V VIN = 4V ~ 12V, Io= 1A 2.450 2.5 2.550 V VIN = 4.8V ~ 12V, Io= 1A 3.235 3.3 3.366 V Output Voltage (Note 4) VIN = 6.5V ~ 12V, Io= 1A 4.900 5.0 5.100 V Line Regulation Vo+1.5V ≤ VIN ≤ 12V, Io= 10mA -- 2 15 mV Load Regulation (Note 1,2) VIN = VOUT +1.5V Io= 10mA ~ 1.0A -- 30 40 mV Dropout Voltage Io= 1A, ∆VOUT = 1% VOUT -- 1.0 1.2 V Quiescent Current VIN = 5V -- 2.5 5 mA Adjustable Pin Current -- 90 -- uA Output Current Limit VIN - VOUT = 3V -- 1.8 -- A Temperature Stability Io=10mA, -- 0.5 -- % Ripple Rejection F= 120Hz, Io= 1A, COUT = 10uF, VIN = Vout+3V -- 60 70 dB Note 1: See thermal regulation specification for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package. Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 10W. Power dissipation is determined by the input / output voltage difference and the output current. Guaranteed maximum power dissipation will not be available over the full input / output voltage range. Note 3: Quiescent current is defined as the minimum output current required to maintain the regulation. Note 4: The Output Capacitor does not have a theoretical upper limit and increasing its value will increase stability COUT=100uF or more is typical for high current regulator design. |
