The LT?1054 is a monolithic, bipolar, switched-capacitor voltage converter and regulator. The LT1054 provides higher output current than previously available converters with significantly lower voltage losses. An adaptive switch driver scheme optimizes efficiency over a wide range of output currents. Total voltage loss at 100mA output current is typically 1.1V. This holds true over the full supply voltage range of 3.5V to 15V. Quiescent current is typically 2.5mA.

The LT1072 has many unique features not found even on the vastly more difficult to use low power control chips presently available. It uses an adaptive anti-sat switch drive to allow very wide ranging load currents with no loss in efficiency. An externally activated shutdown mode reduces total supply current to 50?A typical for standby operation. Totally isolated and regulated outputs can be generated by using the optional ?flyback regulation mode? built into the LT1072, without the need for optocouplers or extra transformer windings.

The LT? 1080/LT1081 are the only dual RS232 driver/ receiver with charge pump to guarantee absolutely no latchup. These interface optimized devices provide a realistic balance between CMOS levels of power dissipation and real world requirements for ruggedness. The driver outputs are fully protected against overload and can be shorted to ?30V. Unlike CMOS, the advanced architecture of the LT1080/LT1081 does not load the signal line when ?shut down? or when power is off. Both the receiver and RS232 outputs are put into a high impedance state. An advanced output stage allows driving higher capacitive loads at higher speeds with exceptional ruggedness against ESD.

The LT ? 1086 is designed to provide up to 1.5A output current. All internal circuitry is designed to operate down to 1V input-to-output differential and the dropout voltage is fully specified as a function of load current. Dropout is guaranteed at several operating points up to a maximum of 1.5V at maximum output current. Dropout decreases at lower load currents. On-chip trimming adjusts the reference/ouput voltage to 1%. Current limit is also trimmed, minimizing the stress on both the regulator and power source circuitry under overload conditions. The LT1086 is pin compatible with older 3-terminal adjustable regulators. A minimum 10?F output capacitor is required on these devices

The LT1086 is pin compatible with older 3-terminal adjustable regulators. A minimum 10?F output capacitor is required on these devices. The LT1086 offers excellent line and load regulation specifications and ripple rejection exceeds 75dB even at the maximum load current of 1.5A. The LT1086 is floating architecture with a composite NPN output stage. All of the quiescent current and the drive current for the output stage flows to the load increasing efficiency. The LT1086 is available in a 3-pin TO-220 package and a space-saving surface mountable 3-pin DD package.
