8 / 21 page 8 FN6934.4 May 25, 2010 Electrical Specifications (ISL21080-50 VOUT = 5.0V) VIN = 6.5V, TA = -40°C to +85°C, IOUT = 0, unless otherwise specified. Boldface limits apply over the operating temperature range, -40°C to +85°C. PARAMETER DESCRIPTION CONDITIONS MIN (Note 12) TYP MAX (Note 12) UNIT VOUT Output Voltage 5.0 V VOA VOUT Accuracy @ TA = +25°C (Notes 7, 8) -0.2 +0.2 % TC VOUT Output Voltage Temperature Coefficient (Note 9) 50 ppm/°C VIN Input Voltage Range 5.5 8.0 V IIN Supply Current 0.5 1.5 µA ΔVOUT /ΔVIN Line Regulation 5.5 V < VIN < 8.0V 80 350 µV/V ΔVOUT/ΔIOUT Load Regulation Sourcing: 0mA ≤ IOUT ≤ 10mA 10 100 µV/mA Sinking: -10mA ≤ IOUT ≤ 0mA 20 350 µV/mA ISC Short Circuit Current TA = +25°C, VOUT tied to GND 80 mA tR Turn-on Settling Time VOUT = ±0.1% with no load 4 ms Ripple Rejection f = 120Hz -40 dB eN Output Voltage Noise 0.1Hz ≤ f ≤ 10Hz 30 µVP-P VN Broadband Voltage Noise 10Hz ≤ f ≤ 1kHz 52 µVRMS Noise Density f = 1kHz 1.1 µV/√Hz ΔVOUT/ΔTA Thermal Hysteresis (Note 10) ΔTA = +165°C 100 ppm ΔVOUT/Δt Long Term Stability (Note 11) TA = +25°C 50 ppm NOTES: 9. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in VOUT is divided by the temperature range; in this case, -40°C to +85°C = +125°C. 10. Thermal Hysteresis is the change of VOUT measured @ TA = +25°C after temperature cycling over a specified range, ΔTA. VOUT is read initially at TA = +25°C for the device under test. The device is temperature cycled and a second VOUT measurement is taken at +25°C. The difference between the initial VOUT reading and the second VOUT reading is then expressed in ppm. For Δ TA = +125°C, the device under test is cycled from +25°C to +85°C to -40°C to +25°C. 11. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm/√1khrs. 12. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not production tested. Typical Performance Characteristics Curves V OUT = 0.9V, VIN = 3.0V, IOUT = 0mA, TA = +25°C unless otherwise specified. FIGURE 2. IIN vs VIN, 3 UNITS FIGURE 3.
