ELECTRICAL CHARACTERISTICS (CIN = 10 mF, COUT = 22 mF Tantalum, VOUT + VDROPOUT < VIN < 7.0 V, 0°C ≤ TA ≤ 70°C, TJ ≤ +150°C, unless otherwise specified, Ifull load = 3.0 A) Characteristic Test Conditions Min Typ Max Unit Adjustable Output Voltage Reference Voltage (Notes 3 and 4) VIN − VOUT = 1.5 V; VAdj = 0 V 10 mA ≤ IOUT ≤ 3.0 A 1.235 (−1.5%) 1.254 1.273 (+1.5%) V Line Regulation 2.0 V ≤ VIN − VOUT ≤ 5.75 V; IOUT = 10 mA − 0.02 0.20 % Load Regulation (Notes 3 and 4) VIN − VOUT = 2.0 V; 10 mA ≤ IOUT ≤ 3.0 A − 0.04 0.4 % Dropout Voltage (Note 5) IOUT = 3.0 A − 1.15 1.40 V Current Limit VIN − VOUT = 3.0 V; TJ ≥ 25°C 3.1 4.6 − A Minimum Load Current (Note 6) VIN = 7.0 V, VAdj = 0 V − 0.6 2.0 mA Adjust Pin Current VIN − VOUT = 3.0 V; IOUT = 10 mA − 50 100 mA Thermal Regulation (Note 7) 30 ms Pulse, TA = 25°C − 0.002 0.020 %/W Ripple Rejection (Note 7) f = 120 Hz; IOUT = 3.0 A; VIN − VOUT = 3.0 V; VRIPPLE = 1.0 VPP − 80 − dB Thermal Shutdown (Note 8) − 150 180 210 °C Thermal Shutdown Hysteresis (Note 8) − − − 25 °C 3. Load regulation and output voltage are measured at a constant junction temperature by low duty cycle pulse testing. Changes in output voltage due to temperature changes must be taken into account separately. 4. Specifications apply for an external Kelvin sense connection at a point on the output pin 1/4” from the bottom of the package. 5. Dropout voltage is a measurement of the minimum input/output differential at full load. 6. Minimum load current is defined as the minimum output current required to maintain regulation. The reference resistor in the output divider is usually sized to fulfill the minimum load current requirement. 7. Guaranteed by design, not 100% functionally tested in production. 8. Guaranteed by design, not 100% parametrically tested in production. However, every part is subject to functional testing for thermal shutdown. PACKAGE PIN DESCRIPTION Package Pin Number Pin Symbol Function TO−220−3 D2PAK−3 1 1 Adj Adjust pin (low side of the internal reference). 2 2 VOUT Regulated output voltage (case). 3 3 VIN Input voltage. |
