4 / 21 page LM2825 SNVS127C – MAY 1997 – REVISED APRIL 2013 www.ti.com LM2825-12 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 LM2825-12 Units (Limits) Typical(2) Limit(3) VOUT Output Voltage 15V ≤ VIN ≤ 40V, 0.1A ≤ ILOAD ≤ 0.75A 12.0 V 11.52/11.40 V(min) 12.48/12.60 V(max) Line Regulation 15V ≤ VIN ≤ 40V 8.5 mV ILOAD = 100 mA Load Regulation 0.1A ≤ ILOAD ≤ 0.75A 12 mV VIN = 24V Output Ripple Voltage VIN = 24V, ILOAD = 1A 100 mV p-p η Efficiency VIN = 24V, ILOAD = 0.5A 87 % (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). LM2825-ADJ 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 18. Symbol Parameter Conditions LM2825-ADJ Units (Limits) Typical(2) Limit(3) VADJ Adjust Pin Voltage 4.5V ≤ VIN ≤ 40V, 0.1A ≤ ILOAD ≤ 1A 1.230 V 1.23V ≤ VOUT ≤ 8V 1.193/1.180 V(min) 1.267/1.280 V(max) η Efficiency VIN = 12V, ILOAD = 0.5A 74 % VOUT Programmed for 3V. See Circuit of Figure 18 (1) When the LM2825 is used as shown in Figure 18 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).
