PARAMETER CONDITIONS (Note 2) Min. AMS2931C Typ. Max. Units Adjustable Version Reference Voltage 1.14 1.20 1.26 V IO ≤ 100 mA, -40°C ≤T J ≤ 125°C, R1=27k, Measured from VOUT to Adjust Pin 1.08 1.32 V Output Voltage Range 3 24 V Line Regulation VOUT + 0.6V ≤V IN ≤ 26V .02 1.5 mV/V Load Regulation 5mA ≤I O ≤ 100 mA 0.3 1 % Dropout Voltage I O ≤ 10 mA I O = 100 mA 0.05 0.3 0.2 0.6 V V Quiescent Current I O = 10 mA I O = 100 mA During Shutdown RL = 500Ω 0.4 15 0.8 1 1 mA mA mA Output Noise Voltage 10Hz-100kHz 100 µV rms/V Output Impedance 100mADC and 10mArms,100Hz=10kHz 40 m Ω Long Term Stability T =1000hr 0.4 %/1000hr Ripple Rejection fO = 120Hz 0.02 %/V Maximum Operational Input Voltage 26 33 V Maximum Line Transient IO = 10mA, Reference Voltage ≤ 1.5V T = 1ms, τ ≤100ms 60 70 V Reverse Polarity Input Voltage, D/C RL = 500Ω, VO ≥ -0.3V -15 -30 V Reverse Polarity Input Voltage, Transient RL = 500Ω, T = 1ms, τ ≤100ms -50 -80 V On/Off Threshold Voltage On Off VO = 3V 3.25 2.0 2.2 1.2 V V On/Off Threshold Current 20 50 µA Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. For guaranteed performance limits and associated test conditions, see the Electrical Characteristics tables. Note 2: See Circuit in Typical Applications. To ensure constant junction temperature, low duty cycle pulse testing is used. Note 3: Limits appearing in boldface type apply over the entire junction temperature range for operation. Limits appearing in normal type apply for TA = TJ = 25°C. Note 4: The junction-to-ambient thermal resistance are as follows: 195 °C/W for the TO-92 (N) package, 160°C/W for the molded plastic SO-8 (S), 50°C/W for the TO-220 package and 73 °C/W for the TO-263 package. If the TO-220 package is used with a heat sink, θ JA is the sum of the package thermal resistance junction-to-case of 3 °C/W and the thermal resistance added by the heat sink and the thermal interface. The thermal resistance of the TO-263 package can be reduced by increasing the PCB copper area thermally connected to the package: using 0.5 square inches of copper area, ϕ JA is 50°C/W; with 1 square inch of copper area ϕ JA is 37°C/W; and with 1.6 or more square inches of copper area ϕ JA is 32°C/W. |
