What are the key features of LTC1550LCMS8-2.5#TRPBF?

Generates -2.5 V regulated negative output from a 2.7 V to 5.25 V input supply with no inductors required
Delivers up to 20 mA output current using a switched-capacitor charge pump architecture
Compact 8-pin MSOP package enables space-efficient negative rail generation on dense PCB layouts
Lead-free (e3) JESD-609 compliant packaging supports RoHS-compliant manufacturing processes

What is LTC1550LCMS8-2.5#TRPBF used for?

The LTC1550LCMS8-2.5#TRPBF is well suited for applications that require a small negative bias voltage from a single positive supply, such as LCD contrast control, op-amp negative rail generation, and sensor biasing circuits. It is commonly used in portable instruments, handheld devices, and battery-powered systems where board space is limited and an inductor-free solution is preferred. Industrial data acquisition front-ends and telecom line cards also benefit from its regulated -2.5 V output with minimal external components.

Frequently Asked Questions

What input voltage range does the LTC1550LCMS8-2.5#TRPBF support, and how does it affect output regulation?

The LTC1550LCMS8-2.5#TRPBF accepts an input voltage from 2.7 V to 5.25 V, making it compatible with 3.3 V and 5 V supply rails. Across this range it maintains a regulated -2.5 V output, though output voltage accuracy may vary slightly near the lower input limit of 2.7 V when load current approaches 20 mA.

Which portable and battery-operated designs benefit most from using LTC1550LCMS8-2.5#TRPBF as a negative rail generator?

Handheld instruments, LCD-biased displays, and single-supply op-amp circuits that need a -2.5 V rail benefit most, since the LTC1550LCMS8-2.5#TRPBF produces up to 20 mA without inductors. Its 2.7 V minimum input allows direct use with a single Li-ion cell or two AA batteries, saving board space compared to boost-inverter alternatives.

How does the 8-pin MSOP package size affect PCB layout for LTC1550LCMS8-2.5#TRPBF?

The 8-pin MSOP footprint measures approximately 3 mm x 3 mm, keeping the total solution size small when combined with only two or four external capacitors typically needed for the charge pump. This compact footprint is ideal for multi-layer PCBs where negative voltage rail routing must fit within tight area budgets of less than 25 mm².

When should a designer choose LTC1550LCMS8-2.5#TRPBF over an inductor-based inverting regulator for generating -2.5 V?

LTC1550LCMS8-2.5#TRPBF is the better choice when load current is at or below 20 mA and EMI from switching inductors is unacceptable, such as in precision analog measurement equipment. Inductor-based inverters offer higher current capacity above 50 mA but introduce magnetic field interference; the switched-capacitor approach avoids this at the cost of current capability.
