AMS1117-3.3
The adjustable and fixed voltage regulators of the AMS1117 series are designed to deliver 1A output current and function down to 1V input-to-output difference. The device's dropout voltage is guaranteed to be 1.3V at maximum output current, dropping at lower load currents. Trimming on-chip adjusts the reference voltage to one percent. The current limit is also reduced, reducing stress on the regulator and energy source circuitry under overload conditions. The AMS1117 devices are pin compatible with existing three-terminal SCSI regulators and are available in low-profile surface mount SOT-223 packages, 8L SOIC packages, and TO-252 (DPAK) plastic packages.

KA431AZ – Programmable Shunt Regulator
The KA431A are three-terminal adjustable regulator series with a guaranteed thermal stability over applicable temperature ranges. The output voltage may be set to any value between VREF (approximately 2.5 volts) and 36 volts with two external resistors These devices have a typical dynamic output impedance of 0.2W Active output circuitry provides a very sharp turn on characteristic, making these devices excellent replacement for zener diodes in many applications.

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.
LM317 IC – Variable Voltage Regulator IC
The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators
LM3940 IC – 1A – Low Dropout Regulator IC
The LM3940 is a 1-A low-dropout regulator designed to provide 3.3 V from a 5-V supply.
The LM3940 is ideally suited for systems which contain both 5-V and 3.3-V logic, with prime power provided from a 5-V bus.
Because the LM3940 is a true low dropout regulator, it can hold its 3.3-V output in regulation with input voltages as low as 4.5 V.
The TO-220 package of the LM3940 means that in most applications the full 1 A of load current can be delivered without using an additional heat sink.
LM7806 IC – 6V Positive Voltage Regulator IC
The LM7806 series of three terminal positive regulators are available in the TO-220 package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
