ELM86xxxxBxA CMOS Dual 400mA LDO Regulator

http://www.elm-tech.com■General description

ELM86xxxxBxA is dual CMOS Voltage Regulator which consists of 2 large current LDOs. With the chipenable function of each channel, it is possible to control on/off independently. This chip enable control ismanaged 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
