MC7805AC/LM340AT–5 Characteristic Symbol Min Typ Max Unit Output Noise Voltage (TA = 25°C) Vn – 10 – µV/VO 10 Hz ≤ f ≤ 100 kHz Output Resistance (f = 1.0 kHz) rO – 0.9 – m Ω Short Circuit Current Limit (TA = 25°C) ISC – 0.2 – A Vin = 35 Vdc Peak Output Current (TJ = 25°C) Imax – 2.2 – A Average Temperature Coefficient of Output Voltage TCVO – –0.3 – mV/ °C NOTES: 1. Tlow = –40°C for MC78XXAC, C, LM340AT–XX, LM340T–XX Thigh = +125°C for MC78XXAC, C, LM340AT–XX, LM340T–XX 2. 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 cycle is used.
