LT1461 TypicalperForMance characTerisTics Characteristic curves are similar for most LT1461s.Curves from the LT1461-2.5 and the LT1461-5 represent the extremes of the voltage options. Characteristic curves for other outputvoltages fall between these curves and can be estimated based on their output.2.5V Transient Response to 10mA2.5V Output NoiseLoad Step2.5V Line Transient Response0.1Hz ≤ f ≤ 10Hz IOUT 0mA 5V V 10mA/DIV IN 4V VOUT V 50mV/DIV OUT 50mV/DIV OUTPUT NOISE (10µV/DIV) 1461 G10 1461 G11 CL = 2µF CIN = 0.1µF TIME (2SEC/DIV) 1461 G12 5V Reference Voltage5V Line Regulationvs Temperature5V Load Regulationvs Temperature 5.0040 2000 0 TEMPCO –60°C TO 120°C V 5.0030 IN = 10V 125°C 3 TYPICAL PARTS 25°C –1 5.0020 1600 –55°C /V) 5.0010 –2 5.0000 1200 –3 4.9990 –4 4.9980 800 4.9970 25°C –5 REFERENCE VOLTAGE (V) 4.9960 LOAD REGULATION (ppm) LINE REGULATION (ppm –6 4.9950 400 125°C –55°C –7 4.9940 SUPPLY ∆ = 14V 6V TO 20V 4.9930 0 –8 –60 –40 –20 0 20 40 60 80 100 120 0.1 1 10 100 –40 –20 0 20 40 60 80 100 120 TEMPERATURE (°C) OUTPUT CURRENT (mA) TEMPERATURE (°C) 1461 G13 1461 G14 1461 G15 5V Minimum Input/Output Voltage5V Supply Current5V Ripple Rejection RatioDifferential vs Load Currentvs Input Voltagevs Frequency 10 10000 100 90 80 1000 70 1 TIO (dB) 60 125°C 25°C 100 50 125°C –55°C 40 0.1 –55°C 30 SUPPLY CURRENT (µA) 10 25°C INPUT/OUTPUT VOLTAGE (V) RIPPLE REJECTION RA 20 10 0.01 1 0 0.1 1 10 100 0 5 10 15 20 25 0.01 0.1 1 10 100 1000 OUTPUT CURRENT (mA) INPUT VOLTAGE (V) FREQUENCY (kHz) 1461 G16 1461 G17 1461fb 1461 G18 6 For more information www.linear.com/LT1461 Document Outline Features Applications Typical Application Description Absolute Maximum Ratings Order Information Pin Configuration Available Options Electrical Characteristics Applications Information Simplified Schematic Package Description Revision History Typical Application Related Parts
