3 / 21 page LM2825 www.ti.com SNVS127C – MAY 1997 – REVISED APRIL 2013 LM2825-3.3 Electrical Characteristics (1) Specifications with standard type face are for TA = 25°C, and those with boldface type apply over full Operating Temperature Range. Test Circuit, see Figure 17. Symbol Parameter Conditions LM2825-3.3 Units (Limits) Typical(2) Limit(3) VOUT Output Voltage 4.75V ≤ VIN ≤ 40V, 0.1A ≤ ILOAD ≤ 1A 3.3 V 3.168/3.135 V(min) 3.432/3.465 V(max) Line Regulation 4.75V ≤ VIN ≤ 40V 1.5 mV ILOAD = 100 mA Load Regulation 0.1A ≤ ILOAD ≤ 1A 8 mV VIN = 12V Output Ripple Voltage VIN = 12V, ILOAD = 1A 40 mV p-p η Efficiency VIN = 12V, ILOAD = 0.5A 75 % (1) When the LM2825 is used as shown in Figure 17 test circuit, system performance will be as shown in Electrical Characteristics. (2) Typical numbers are at 25°C and represent the most likely norm. (3) All limits ensured at room temperature (standard type face) and at temperature extremes (bold type face) when output current is limited to the value given in the temperature derating curves. See the Application Information section for curves. All limits at temperature extremes are ensured using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
