LOW SATURATION VOLTAGE REGULATOR

www.DataSheet4U.com ELM99xxxA ■ GENERAL DESCRIPTION LOW SATURATION VOLTAGE REGULATOR 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 ・ 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 : 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 ・ Palmtops ・ cameras and video recorders ・ Battery-operated devices ■ APPLICATION ・ Cellular telephones ・ Laptop and notebook computers ・ Reference voltage sources ・ PCMCIA cards ■ PIN CONFIGURATION 1.ELM99xx1A 2.ELM99xx2A 5 4 3.ELM99xx3A 5 4 SOT-89 SOT-89-5 SOT-89-5 1 2 3 1 2 3 1 2 3 ( TOP VIEW ) ( TOP VIEW ) ( TOP VIEW ) SOT-89 Pin No. Pin Name 1 VSS 2 VIN 3 VOUT SOT-89-5 Pin No. Pin Name 1 VSS 2 VIN 3 VOUT 4 NC 5 CE SOT-89-5 Pin No. Pin Name 1 VSS 2 VIN 3 VOUT 4 NC 5 CE 220 LOW SATURATION VOLTAGE REGULATOR ■ SELECTION GUIDE Symbol Ex a, b Output Voltage 27 : VOUT = 2.7V 30 : VOUT = 3.0V 33 : VOUT = 3.3V 50 : VOUT = 5.0V CE = "L"active CE = "H"active A Version ELM99xxxA ELM99 x x x A ↑↑↑↑ a b c d c d CE Selection Product Version 1: 2: 3: A: ■ MARKING ELM99xx1A SOT-89 ① : Represents the integer digit of the Output Voltage Symbol A B C Symbol A B C D E Output Voltage 2.*V 3.*V 4.*V Output Voltage *.0V *.1V *.2V *.3V *.4V Symbol F G H J K Output Voltage *.5V *.6V *.7V *.8V *.9V Symbol D E Output Voltage 5.*V 6.*V ① ② ③ ④ ② : Represents the decimal digit of the Output Voltage ③ : Represents the assembly lot number A ～ Z repeated (I,O,X excepted) ④ : Represents the assembly lot number 0 ～ 9 repeated 221 LOW SATURATION VOLTAGE REGULATOR ELM99xxxA ELM99xx2A SOT-89-5 ① : Represents the integer digit of the Output Voltage Symbol Output Voltage 2.*V 3.*V 4.*V Output Voltage *.0V *.1V *.2V *.3V *.4V Symbol J K Output Voltage 5.*V 6.*V F G H ① ② ③ ④ ② : Represents the decimal digit of the Output Voltage Symbol A B C D E 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 L M N Output Voltage 2.*V 3.*V 4.*V Symbol P Q 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 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 222 LOW SATURATION VOLTAGE REGULATOR ■ BLOCK DIAGRAM ELM99xx1A VIN VOUT ELM99xxxA ELM99xx2A, ELM99xx3A VIN VOUT + Protect Circuit + Protect Circuit Vref Vref VSS Control Circuit VSS CE/CE * CE : ELM99xx2A, CE : ELM99xx3A ■ STANDARD CIRCUIT ELM99xx1A ELM99xx2A, ELM99xx3A Control Voltage CE/CE VIN VIN VOUT VOUT CO VSS VIN VIN ELM99xx1A ELM99xx2A ELM99xx3A VSS VOUT VOUT CI CI CO * CE : ELM99xx2A, CE : ELM99xx3A ■ MAXIMUM ABSOLUTE RATINGS Parameter Input Voltage CE/CE Input Voltage Output Voltage Output Current Power Dissipation Operating Temperature Storage Temperature Sym.
