4 / 9 page 4 GM317 3-TERMINAL 1.5A ADJUSTABLE REGULATOR Electrical Characteristics (Unless otherwise noted, VI - VO = 5V and IO= 0.5A. TJ = Full Range, unless otherwise noted) Parameter Symbol Test Condition Min Typ Max Unit 3V ≤ VIN – VOUT ≤ 40V, TJ = 25°C 0.01 0.04 Line Regulation (note 2) ΔVOI 3V ≤ VIN – VOUT ≤ 40V, 0.02 0.07 %/V VOUT = 10V, f = 120Hz 65 Ripple Rejection Ratio VOUT = 10V, f = 120Hz, 10μF capacitor between ADJ and GND 66 80 dB VO ≤ 5V 5 25 mV 10mA ≤ IOUT ≤ 1.5A, TJ = 25°C VO > 5V 0.1 0.5 % VO ≤ 5V 20 70 mV Load regulation (note 3) ΔVOL 10mA ≤ IOUT ≤ 1.2A VO > 5V 0.3 1.5 % Output Voltage Change with Temperature ΔVOT Full Temperature Range % Long Term Stability (Note 4) TJ = 125 OC, VIN – VOUT = 40V, after 1000hr 0.3 1 % Output Noise Voltage 10Hz ≤ f ≤ 10KHz, TJ = 25°C 0.003 % Minimum Load Current VIN – VOUT ≤ 40V 3.5 10 mA VIN – VOUT ≤ 15V 1.5 2.2 Output Current Limit ICL VIN – VOUT ≤ 40V, TJ = 25°C 0.15 0.4 A Adjustment Pin Current IADJ 50 100 µA Adjustment Pin Current Change ΔIADJ 3V ≤ VIN – VOUT ≤ 40V 10mA ≤ IOUT ≤ 1.2A 0.2 5.0 µA Reference Voltage 3V ≤ VIN – VOUT ≤ 40V, 10mA ≤ IOUT ≤ 1.5A, P ≤ 15W 1.2 1.25 1.3 V Note 1: All characteristics are measured with a 0.1µF capacitor across the input and a 1µF capacitor across the output. Note 2: Input regulation is expressed here as the percentage change in output voltage per 1V change at the input. Note 3: Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible. Thermal effects must be taken into account separately. Note 4: Since long-term drift cannot be measured on the individual devices prior to shipment, this specification is not intended to be a guarantee or warranty. It is an engineering estimate of the average drift to be expected from lot to lot. |
