ELM86xxxxBxA CMOS Dual 400mA LDO Regulator ■General description ELM86xxxxBxA is dual CMOS Voltage Regulator which consists of 2 large current LDOs. With the chip enable function of each channel, it is possible to control on/off independently. This chip enable control is managed by positive logic. The standby current is designed to be Typ.0.1μA. ELM86 series is available only in SOT-26 PKG, while the output voltage is fixed within the range of 1.2 to 4.0V. The internal short protection function will limit output current when VOUT pin is in short condition; meanwhile, thermal protection circuit will shut off the output voltage and current when an unusual high chip temperature is detected. ■Features • • • • • • • Output voltage range : 1.2V to 4.0V (by 0.1V) Input-output voltage difference : Typ.120mV(Vout=3.0V, Iout=100mA) Standby current consumption : Typ.0.1μA Current consumption : Typ.25μA Input stability : Typ.0.02%/V(Iout=40mA) Load stability : Typ.5mV(1mA≤Iout≤100mA) Accuracy of output voltage : ±2.0%(Vout>1.5V), ±30mV(Vout≤1.5V) • Short circuit current limiter : Typ.40mA(Vout=0V) • Thermal shutdown protection : Typ.165°C • Package : SOT-26 ■Application • • • • Portable electronics Wireless devices Cell phones Battery-operated devices ■Maximum absolute ratings Parameter Input voltage CE1,CE2 Input voltage Vout1,Vout2 voltage Output current Iout1+Iout2 Power dissipation Thermal resistance junction to ambient Operationg Temperature Storage Temperature Symbol Vin Vce Vout Iout Pd Rθja Top Tstg 13 - 1 Limit Vss-0.3 to 10.0 Vss-0.3 to Vin+0.3 Vss-0.3 to Vin+0.3 800 300 400 -40 to +85 -55 to +125 Unit V V V mA mW °C/W °C °C Rev.1.0 ELM86xxxxBxA CMOS Dual 400mA LDO Regulator ■Selection guide ELM86xxxxBxA-S Symbol a, b c, d e f g h e.g. : 12: Vout=1.2V 18: Vout=1.8V 30: Vout=3.0V 33: Vout=3.3V e.g. : Output voltage2 12: Vout=1.2V 18: Vout=1.8V (Vout2) 30: Vout=3.0V 33: Vout=3.3V Package B: SOT-26 1: Type1 Pin configuration type 2: Type2 Product version A Taping direction S: Refer to PKG file Output voltage1 (Vout1) ELM86 x x x x B x A - S ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ a b c d e f g h ■Pin configuration SOT-26(TOP VIEW) ELM86xxxxB1A Pin No. 1 2 3 4 5 6 Pin name VOUT2 VSS CE2 * CE1 * VIN VOUT1 ELM86xxxxB2A Pin No. 1 2 3 4 5 6 Pin name CE1 * VIN CE2 * VOUT2 VSS VOUT1 * CE1, CE2 : Active High ■Standard circuit 13 - 2 Rev.1.0 ELM86xxxxBxA CMOS Dual 400mA LDO Regulator ■Block diagram VOUT1 VIN VOUT2 Vref + Vref Protect Circuit CE1 Control Circuit 1 CE2 Control Circuit 2 + Protect Circuit VSS ■Electrical characteristics Vout1=Vout2=1.2V(ELM861212BxA) Top=25°C Parameter Symbol Condition Min.
