ELM99xxxA LOW SATURATION VOLTAGE REGULATOR ■ GENERAL DESCRIPTION ELM99xxxA series is CMOS voltage regulator providing large current. It consists of devices including reference voltage source, error amplifier, low resistance output transistor, short-circuit protection circuit, output voltage setting resistor, chip-enable circuit. Output voltage is fixed internally with high accuracy. ELM99xxxA provides excellent characteristics, such as small input-output voltage difference due to low resistance output transistor, high load stability due to high gain error amplifier. The chip-enable function is available in three selections, no-chip enable function, active-low (“L” active) and active-high (“H” active). The package is SOT-89-3 or SOT-89-5. SOT-89-5 is used for chip enable version. ■ FEATURES ・ Maximum output current : 300mA (Intenal current limiter operates in case load current exceeds 300mA.) : ± 2.0% : TYP. 140mV (ELM9930xA IOUT=40mA) : TYP. 0.1 μ A (ELM99xx3A) : TYP. 5mV (1mA ≦ Iout ≦ 100mA) : TYP. 0.15%/V (ELM9930xA IOUT=40mA) : 2.0V ～ 6.0V ( 0.1V steps ) : TYP. 70mA (VOUT=0V) : “L”active ELM99xx2A, “H”active ELM99xx3A ・ High accuracy of output voltage ・ Small input-output voltage differential ・ Low stand-by current consumption ・ High load stability ・ High input stability ・ Output voltage range ・ Short-circuit current limiter ・ Chip-enable pin available ■ APPLICATION ・ Cellular telephones ・ Laptop and notebook computers ・ Reference voltage sources ・ Palmtops ・ cameras and video recorders ・ Battery-operated devices ・ PCMCIA cards ■ PIN CONFIGURATION 1.ELM99xx1A 2.ELM99xx2A 5 2 4 5 SOT-89-5 SOT-89 1 3.ELM99xx3A 3 ( TOP VIEW ) SOT-89 Pin No. Pin Name 1 VSS 2 VIN 3 VOUT 1 2 SOT-89-5 3 ( TOP VIEW ) SOT-89-5 Pin No. Pin Name 1 VSS 2 VIN 3 VOUT 4 NC 5 CE 220 4 1 2 3 ( TOP VIEW ) SOT-89-5 Pin No. Pin Name 1 VSS 2 VIN 3 VOUT 4 NC 5 CE LOW SATURATION VOLTAGE REGULATOR ELM99xxxA ■ SELECTION GUIDE Symbol Ex a, b 27 : VOUT = 2.7V 30 : VOUT = 3.0V 33 : VOUT = 3.3V 50 : VOUT = 5.0V Output Voltage c CE Selection d Product Version 1: 2: 3: A: ELM99 x x x A ↑↑↑↑ a b c d CE = "L"active CE = "H"active A Version ■ MARKING ELM99xx1A SOT-89 ① ③ ② ④ ① : Represents the integer digit of the Output Voltage Symbol A Output Voltage 2.*V B 3.*V C 4.*V Symbol D E Output Voltage 5.*V 6.*V ② : Represents the decimal digit of the Output Voltage Symbol A B C D E Output Voltage *.0V *.1V *.2V *.3V *.4V Symbol F G H J K ③ : Represents the assembly lot number A ～ Z repeated (I,O,X excepted) ④ : Represents the assembly lot number 0 ～ 9 repeated 221 Output Voltage *.5V *.6V *.7V *.8V *.9V LOW SATURATION VOLTAGE REGULATOR ELM99xxxA ELM99xx2A SOT-89-5 ① : Represents the integer digit of the Output Voltage Symbol ① ③ ② ④ Output Voltage Symbol Output Voltage F 2.*V J 5.*V G H 3.*V 4.*V K 6.*V ② : Represents the decimal digit of the Output Voltage Symbol A B C D E Output Voltage *.0V *.1V *.2V *.3V *.4V Symbol F G H J K Output Voltage *.5V *.6V *.7V *.8V *.9V ③ : Represents the assembly lot number A ～ Z repeated (I,O,X excepted) ④ : Represents the assembly lot number 0 ～ 9 repeated ELM99xx3A ① : Represents the integer digit of the Output Voltage Symbol Output Voltage Symbol Output Voltage L 2.*V P 5.*V M N 3.*V 4.*V Q 6.*V ② : Represents the decimal digit of the Output Voltage Symbol A B C D E Output Voltage *.0V *.1V *.2V *.3V *.4V Symbol F G H J K ③ : Represents the assembly lot number A ～ Z repeated (I,O,X excepted) ④ : Represents the assembly lot number 0 ～ 9 repeated 222 Output Voltage *.5V *.6V *.7V *.8V *.9V LOW SATURATION VOLTAGE REGULATOR ELM99xxxA ■ BLOCK DIAGRAM ELM99xx1A ELM99xx2A, ELM99xx3A VIN VIN VOUT VOUT - - + + Protect Circuit Protect Circuit Vref Vref Control Circuit VSS VSS CE/CE * CE : ELM99xx2A, CE : ELM99xx3A ■ STANDARD CIRCUIT ELM99xx1A ELM99xx2A, ELM99xx3A Control Voltage CE/CE VIN VIN ELM99xx1A VOUT CI VIN VOUT CO VIN ELM99xx2A ELM99xx3A CO CI VSS VSS * CE : ELM99xx2A, CE : ELM99xx3A ■ MAXIMUM ABSOLUTE RATINGS Parameter Input Voltage CE/CE Input Voltage Output Voltage Output Current Power Dissipation Operating Temperature Storage Temperature (VSS=0V) Units Sym.
