LT1026IS8#TRPBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1026IS8#TRPBF is a switched capacitor voltage doubler and inverter manufactured by Analog Devices Inc. It operates from an input voltage range of 4V to 10V, providing dual outputs of ±7V to ±18V. The device delivers output currents exceeding 10mA using two internal charge pumps that first double the input voltage and then invert it. Manufactured in bipolar technology, it is not susceptible to latch-up and can generate up to 36V. It is housed in an 8-lead SOIC package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated dual charge pump topology for simultaneous voltage doubling and inversion
• Bipolar manufacturing process ensures immunity to latch-up conditions
• Capable of generating high voltage differentials up to 36V from low input sources

Voltage Regulators - DC DC Switching Regulators Applications

• Dual polarity power supply generation for operational amplifiers
• Bias voltage generation for analog signal processing circuits
• Powering RS-232 transceivers requiring negative voltage rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the manufacturer is Analog Devices Inc. or its predecessor Linear Technology. Ensure the part number matches the exact SOIC-8 configuration required for your PCB footprint. Cross-reference with official distributor catalogs to validate authenticity and current availability status before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed to generate dual positive and negative voltages from a single low-voltage source. It is suitable for applications requiring moderate current levels above 10mA without the complexity of magnetic components. Consider the operating temperature range of -40°C to +85°C for environmental compatibility. Evaluate the need for bipolar technology benefits such as latch-up immunity over CMOS alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1026 series of switched capacitor converters. It shares functional similarities with other LT102x family members but differs in packaging and specific electrical tolerances. The IS8 variant specifically denotes the industrial temperature range and SOIC-8 surface mount package. It serves as a monolithic alternative to discrete capacitor-diode multiplier circuits.
