LP38690-ADJ/LP38692-ADJ Low Dropout CMOS Linear Regulators with
Adjustable Output
Stable with Ceramic Output Capacitors
General DescriptionThe LP38690/2-ADJ low dropout CMOS linear regulators
provide 2.5% precision reference voltage, extremely low
dropout voltage (450mV@1A load current, VOUT= 5V) and
excellent AC performance utilizing ultra low ESR ceramic
output capacitors.
The low thermal resistanceofthe LLP and SOT-223 pack-
ages allowthefull operating currenttobe used evenin high
ambient temperature environments.
The useofa PMOS power transistor means thatnoDC base
drive currentis requiredto biasit allowing groundpin current remain below 100 µA regardlessof load current, input
voltage,or operating temperature.
Dropout Voltage: 450 mV (typ)@1A (typ.5V out).
Ground Pin Current:55µA (typ)atfull load.
Adjust Pin Voltage: 2.5% (25˚C) accuracy.
Features Output voltage rangeof 1.25V-9V 2.5% adjustpin voltage accuracy (25˚C) Low dropout voltage: 450mV@1A (typ,5V out) Wide input voltage range (2.7Vto 10V) Precision (trimmed) bandgap reference Guaranteed specsfor -40˚Cto +125˚C 1µA off-state quiescent current Thermal overload protection Foldback current limiting SOT-223 and 6-Lead LLP packages Enablepin (LP38692-ADJ)
