7 / 28 page 7 www.fairchildsemi.com LM78XX/LM78XXA Rev. 1.0.1 Electrical Characteristics (LM7810) (Continued) Refer to the test circuits. -40°C < TJ < 125°C, IO = 500mA, VI = 16V, CI = 0.33µF, CO = 0.1µF, unless otherwise specified. Notes: 9. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty is used. 10. These parameters, although guaranteed, are not 100% tested in production. Symbol Parameter Conditions Min. Typ. Max. Unit VO Output Voltage TJ = +25°C 9.6 10.0 10.4 V 5mA ≤ IO ≤ 1A, PO ≤ 15W, VI = 12.5V to 25V 9.5 10.0 10.5 Regline Line Regulation(9) TJ = +25°C VI = 12.5V to 25V – 10.0 200 mV VI = 13V to 25V – 3.0 100 Regload Load Regulation(9) TJ = +25°C IO = 5mA to 1.5A – 12.0 200 mV IO = 250mA to 750mA – 4.0 400 IQ Quiescent Current TJ = +25°C – 5.1 8.0 mA ∆IQ Quiescent Current Change IO = 5mA to 1A – – 0.5 mA VI = 12.5V to 29V – – 1.0 ∆VO/∆T Output Voltage Drift(10) IO = 5mA – -1.0 – mV/°C VN Output Noise Voltage f = 10Hz to 100kHz, TA = +25°C – 58.0 – µV/VO RR Ripple Rejection(10) f = 120Hz, VO = 13V to 23V 56.0 71.0 – dB VDROP Dropout Voltage IO = 1A, TJ = +25°C – 2.0 – V rO Output Resistance(10) f = 1kHz – 17.0 – m Ω ISC Short Circuit Current VI = 35V, TA = +25°C – 250 – mA IPK Peak Current(10) TJ = +25°C – 2.2 – A |
