5 / 12 page ISL21070 5 FN7599.0 March 19, 2010 Electrical Specifications (ISL21070-33, VOUT = 3.3V) VIN = 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. SYMBOL PARAMETER CONDITIONS MIN (Note 10) TYP MAX (Note 10) UNIT VOUT Output Voltage 3.3 V VOA VOUT Accuracy @ TA = +25°C ISL21070 C-grade -0.2 +0.2 % TC VOUT Output Voltage Temperature Coefficient (Note 7) ISL21070 C-grade 50 ppm/° C VIN Input Voltage Range 3.5 5.5 V IIN Supply Current VEN = VIN 25 µA ΔVOUT/ΔVIN Line Regulation 3.5V < VIN < 5.5V 50 100 ΔVOUT/ΔIOUT Load Regulation Sourcing: 0mA ≤ IOUT ≤ 10mA 20 70 µV/mA Sinking: -10mA ≤ IOUT ≤ 0mA 20 70 µV/mA ISC Short Circuit Current TA = +25°C, VOUT tied to GND 30 mA tR Turn-on Settling Time VOUT = ±0.1% 150 µs Ripple Rejection f = 10kHz -20 dB eN Output Voltage Noise 0.1Hz ≤ f ≤ 10Hz 30 µVP-P VN Broadband Voltage Noise 10Hz ≤ f ≤ 10kHz 10 µVRMS ΔVOUT/ΔTA Thermal Hysteresis (Note 8) ΔTA = +125°C 100 ppm ΔVOUT/Δt Long Term Stability (Note 9) TA = +25°C 50 ppm NOTES: 7. 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. 8. 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. 9. Long term drift is logarithmic in nature and diminishes over time. Drift after the first 1000 hours will be approximately 10ppm/√1khrs 10. 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. |
