LM1085-ADJ (LM1085) – 3A Adjustable Low Dropout (LDO) Positive Voltage Regulator
The LM1085 is a regulator with a maximum dropout of 1.5 V at 3 A of load current. It has the same pin-out as TI?s industry standard LM317.
Two resistors are required to set the output voltage of the adjustable output voltage version of the LM1085. Fixed output voltage versions integrate the adjust resistors.
The LM1085 circuit includes a zener trimmed bandgap reference, current limiting and thermal shutdown.
LM1086CT-ADJ (LM1086) – 1.5A Adjustable Low Dropout (LDO) Positive Voltage Regulator
The LM1086 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 1.5A of load current. It has the same pin-out as industry standard LM317.
The LM1086 is available in an adjustable version, which can set the output voltage with only two external resistors. It is also available in six fixed voltages: 1.8V, 2.5V, 2.85V, 3.3V, 3.45V and 5.0V. The fixed versions integrate the adjust resistors. The LM1086 circuit includes a zener trimmed bandgap reference, current limiting and thermal shutdown.
LM1117 3.3V Low Dropout Voltage Regulator IC
The REF03 precision voltage reference provides a stable 2.5 V output, with minimal change for variations in supply voltage, ambient temperature, or loading conditions. Single-supply operation over an input voltage range of 4.5 V to 33 V with a current drain of 1 mA and good temperature stability is achieved using an improved band gap design. Primarily targeted at price sensitive applications, the REF03 is available in plastic mini DIPs and surface-mount small outline plastic packages. For improved performance or ?40?C to 125?C operation, see the ADR03 data sheet.
