ELM85xxxxA CMOS 600mA/800mA LDO voltage regulator ■General description ELM85xxxxA is CMOS voltage regulator which is characterized with high current and low dropout (55mV at Iout=100mA). There are 2 types of CE selection of ELM85 series: non-chip enable function and “H” active. The standard output voltages are 3.0V, 3.3V, 5.0V. ELM85 series can also be made as semi-custom IC within the range of 0.8V to 5.0V by 0.1V step. This series also includes short circuit current limiter and thermal shutdown circuit. Ceramic capacitors with low ESR can be used as input and output ones. ■Features • Output voltage range • Output current • • • • • • • : 0.8V to 5.0V (by 0.1V) : 600mA(Vout<3.0V) 800mA(Vout≥3.0V) Current consumption : Typ.40μA : Typ.0.02%/V Input stability Load stability : Typ.20mV(1mA≤Iout≤300mA) Accuracy of output voltage : ±2.0% Input-output voltage difference : Typ.55mV(Vout=3.0V, Iout=100mA) : Typ.70mA(Vout=0V) Short circuit current limiter Package : SOT-223(0.8V to 5.0V), SON8-3x3(1.2V to 4.0V) SOT-89(1.2V to 4.0V), SOT-89-5(1.2V to 4.0V) SOT-23(1.2V to 4.0V), SOT-25(1.2V to 4.0V) (0.8V to 1.1V, 4.1V to 5.0V are available in SOT-223 package only.) ■Application • Battery operated devices • Portable AV equipments ■Maximum absolute ratings Input voltage Output voltage Output current Parameter Power dissipation Operating temperature Storage temperature Symbol Vin Vout Iout Limit Vss-0.3 to 7.0 Vss-0.3 to Vin+0.3 1000 500 (SOT-89) 500 (SOT-89-5) 250 (SOT-23) 300 (SOT-25) 500 (SON8-3x3) 625 (SOT-223) -40 to +85 -55 to +125 Pd Top Tstg 14 - 1 Unit V V mA mW °C °C Rev.1.3 ELM85xxxxA CMOS 600mA/800mA LDO voltage regulator ■Selection guide ELM85xxxxA-x Symbol a, b Output voltage c CE selection e.g. : 30: Vout=3.0V, 33: Vout=3.3V 50: Vout=5.0V 1: NO CE 3: CE=“H” active ELM85 x x x x A - x ↑ ↑ ↑ ↑ ↑ ↑ a b c d e f A: SOT-89, SOT-89-5 B: SOT-23, SOT-25 Package G: SON8-3x3 H: SOT-223 Product version A S: Refer to PKG file (SOT-223: S only) Taping direction N: Refer to PKG file d e f ■Pin configuration SOT-223(TOP VIEW) SOT-89(TOP VIEW) SOT-89-5(TOP VIEW) 5 TAB 1 3 2 1 ELM85xx1HA Pin No. Pin name 1 VSS 2/TAB VIN 3 VOUT 2 1 2 2 3 ELM85xx3AA Pin No. Pin name 1 VSS 2 VIN 3 VOUT 4 NC 5 CE ELM85xx1AA Pin No. Pin name 1 VSS 2 VIN 3 VOUT SOT-23(TOP VIEW) 3 1 3 4 SOT-25(TOP VIEW) ELM85xx1BA Pin No. Pin name 1 VSS 2 VOUT 3 VIN 4 5 1 14 - 2 2 3 ELM85xx3BA Pin No. Pin name 1 VIN 2 VSS 3 CE 4 NC 5 VOUT Rev.1.3 ELM85xxxxA CMOS 600mA/800mA LDO voltage regulator SON8-3x3(TOP (TOP VIEW) VIEW) (TOP VIEW) 8 7 85 6 6 7 SON8-3x3(BOTTOM VIEW) (BOTTOM VIEW) (BOTTOM VIEW) 5 5 2 14 3 3 2 4 4 6 7 8 3 2 1 * * 1 58 7 6 2 3 41 ELM85xx3GA Pin No. Pin name Pin No. Pin name 1 VOUT 5 NC 2 VOUT 6 CE 3 VIN 7 NC 4 VIN 8 VSS * The potential of the tab on the back is the circuit one (VIN).
