| ILA8137 +5.1 V +5.1 V REGULATOR WITH DISABLE AND RESET The ILA8137A is a monolithic dual positive voltage regulator designed to provide fixed precision output voltages of 5.1V at current up to 0,75 A. An internal reset circuit generates a reset pulse when the output 1 decreases below the regulated voltage value. Output 2 can be disabled by TTL input . Short circuit and thermal protections are included in ILA8137 * Output Currents up to 1 A * Fixed precision output voltage 5.1 V 2% * Output 1 with reset facility * Output 2 With Disable by TTL input * Shot-circuit protection at both outputs * Thermal protection * Lowdrop output voltage * Available also in heptawatt package BLOCK DIAGRAM I nput 1 REFERENCE 7 1 Heptawat 1 - Input 1 2 - Input 2 3 - Disable 4 - Ground 5 - N. c. 6 - Output 2 7 - Output 1 OUT1 7 5 Output 1 Reset CR PROTECTI ON RESET 2 6 Delay capacitor Output 2 Disable 3 DI SABLE OUT2 4 ABSOLUTE MAXIMUM RATINGS Parameter DC Input Voltage Pin 1 Disable Input Voltage Output Voltage at Pin 5 Storage Temperature Junction Temperature Symbol VI VDIS VRST Tstg TJ Value 20 20 20 -65 to +150 0 to +150 Unit V V V C C 1 ILA8137 THERMAL DATA Parameter Maximum Thermal Resistance JunctionCase for Heptawatt Maximum Recommended Junction Temperature Symbol R th(j-c) TJ Value 6 130 Unit C /W C VI C1 TYPICAL APPLICATION C2 Delcap 2 5 7 1 VO1 VO2 C3 C4 Reset ILA8137 6 3 4 Disable C1,3,4=10 F, C2=0,1 F ELECTRICAL CHARACTERISTICS (VI = 7V, TJ = +25 C, unless otherwise specified) Parameter Output Voltage IO1,2 = 10 mA Output Voltage 7 V < VI < 14 V 5 mA < IO1,2 < 750 mA Dropout Voltage IO1,2 = 750 mA IO1,2 = 1 A Line Regulation 7 V < VI < 14 V, I O1,2 = 200 mA Load Regulation 5 mA < IO1,2 < 0.6 A Quiescent Current IO1= 10 mA, Output 2 Disabled Reset Thrseshold Voltage (K = VO1) Reset Thrseshold Hysteresis Seturation Voltage in Reset Condition I5 = 5 mA Leakage Current in Normal Condition at Pin 5 V5 = 10 V Short Circuit Output Current VI = 7 V VI= 16V Disable Voltage High (out 2 active) Disable Voltage Low (out 2 disable) Disable Bias Current 0V < VDIS < 7V Symbol VO1,2 VO1,2 Min 5 4.9 Max 5.2 5.3 Unit V V VIO1,2 VIO1,2 UO1,2LI UO1,2LO IQ VO1RST VRSH VRL IRH I O1,2SC I O1,2SC VDISH VDISL IDIS K-0.4 20 1.4 2 50 100 2.0 K-0.1 75 0.4 10 V V mV mV mA V V V A A A V V A 2 -100 1.6 1 0.8 2 2 |
