ELM88xxxxA CMOS 300mA LDO Voltage regulator ■General description ELM88xxxxA is high current and low dropout(LOD) CMOS fixed voltage regulator. There are 2 types of CE selection for ELM88 series: non-chip enable function and “H”active. Thermal shutdown protective function and short circuit current limiter are included in the IC. The standard output voltages are 1.2V, 1.8.V, 2.5V, 3.0V, 3.3V, 5.0V; ELM88 series can also be designed as semi-custom IC within the range of 0.8V to 5.0V by 0.1V step. ■Features • • • • • • • • • • • Output voltage range Output current Stand by current consumption Input stability Load stability Accuracy of output voltage Input-output voltage difference Short circuit current limiter Thermal shutdown protection Chip enable pin Package : 0.8V to 5.0V (by 0.1V) : Min.300mA : Typ.0.1μA : Typ.0.02%/V(Iout=40mA) : Typ.5mV(1mA≤Iout≤100mA) : ±2.0%(Vout>1.5V), ±30mV(Vout≤1.5V) : Typ.350mV(Vout=3.0V, Iout=300mA) : Typ.40mA(Vout=0V) : Typ.165°C : “H”active(ELM88xx3xA) : SOT-89, SOT-89-5, SOT-23, SOT-25, SC-70-5(SOT-353) ■Application • • • • Battery operated devices Camera and Video recorders Reference voltage source Portable electronics ■Maximum absolute ratings Parameter Input voltage CE Input voltage Output voltage Output current Power dissipation Operationg Temperature Storage Temperature Symbol Vin Vce Vout Iout Limit Vss-0.3 to 7.0 Vss-0.3 to Vin+0.3 Vss-0.3 to Vin+0.3 600 500 (SOT-89) 500 (SOT-89-5) 250 (SOT-23) 250 (SOT-25) 150 (SC-70-5)(SOT-353) -40 to +85 -55 to +125 Pd Top Tstg 21 - 1 Unit V V V mA mW °C °C Rev.1.1 ELM88xxxxA CMOS 300mA LDO Voltage regulator ■Selection guide ELM88xxxxA-x Symbol a, b Output voltage c CE selection d Package e Product version f Taping direction e.g. : 12: Vout=1.2V 18: Vout=1.8V 25: Vout=2.5V 30: Vout=3.0V 33: Vout=3.3V 50: Vout=5.0V 1: No CE 3: CE="H"active A: SOT-89, SOT-89-5 B: SOT-23, SOT-25 C: SC-70-5(SOT-353) A S: Refer to PKG file N: Refer to PKG file ELM88 x x x x A - x ↑ ↑ ↑ ↑ ↑ ↑ a b c d e f ■Pin configuration SOT-89(TOP VIEW) SOT-89-5(TOP VIEW) ELM88xx3AA Pin No. 1 2 3 4 5 ELM88xx1AA Pin No. 1 2 3 Pin name VSS VIN VOUT SOT-23(TOP VIEW) SOT-25(TOP VIEW) Pin No. 1 2 3 SC-70-5(TOP VIEW) Pin name VSS VOUT VIN ELM88xx1CA Pin No. 1 2 3 4 5 Pin name NC VIN NC VSS VOUT ELM88xx3BA Pin No. 1 2 3 4 5 ELM88xx1BA SC-70-5(TOP VIEW) 21 - 2 Pin name VSS VIN VOUT NC CE Pin name VSS VIN VOUT NC CE ELM88xx3CA Pin No. 1 2 3 4 5 Pin name VSS VIN VOUT NC CE Rev.1.1 ELM88xxxxA CMOS 300mA LDO Voltage regulator ■Standard circuit ELM88xx1xA ELM88xx3xA * Ci=1μF, Co=1μF or greater * Ci=1μF, Co=1μF or greater ■Block diagram ELM88xx1xA ELM88xx3xA ■Electrical characteristics (ELM88xx1xA) Vout=1.2V(ELM88121xA), No CE pin Parameter Symbol Condition Output voltage Vout Vin=2.2V, Iout=40mA Output current Iout Vin=3.0V Input stability ΔVout/ΔVin Iout=40mA, 1.7V≤Vin≤6.0V Load stability ΔVout/ΔIout 1mA≤Iout≤100mA, Vin=2.2V Input-Output voltage differential Vdif Iout=100mA Current consumption Iss Vin=2.2V, No-load Input voltage Vin Output voltage -40°C≤Top≤+85°C, ΔVout/ΔTop temperature coefficient Iout=40mA, Vin=2.2V Short circuit current Ilim Vout=0V Ripple rejection ratio RR f=1kHz, Iout=40mA Thermal shutdown temparature Tsd Output noise Vno BW=10Hz to 100kHz 21 - 3 Top=25°C Min.
