Key Features
- Fixed -3 V negative output LDO with only 0.38 V nominal dropout voltage for high efficiency
- Wide input voltage range from 4 V to 10 V with 12 V absolute maximum for robust designs
- Ultra-compact SOT-23 3-pin package minimizing board real estate in space-constrained applications
Applications
The TC593002ECBTR suits battery-powered and portable equipment that requires a stable negative supply rail for op-amps, analog front-ends, or audio circuits. Its low 0.38 V nominal dropout voltage maximizes efficiency in systems where the input voltage is close to the regulated -3 V rail. The small SOT-23 footprint makes it ideal for wearables, handheld instrumentation, and mixed-signal PCBs with tight space budgets.

Frequently Asked Questions
What is the dropout voltage specification for the TC593002ECBTR and why does it matter for battery-powered designs?
The TC593002ECBTR has a nominal dropout voltage of 0.38 V and a maximum of 0.6 V. In battery-powered designs, this low dropout extends usable battery life by allowing regulation to continue even when the input supply drops to within 0.6 V of the -3 V output rail.
What input voltage range does the TC593002ECBTR support, and what is its absolute maximum input rating?
The device operates from 4 V to 10 V input, with an absolute maximum input voltage of 12 V. Exceeding 12 V risks permanent damage, so designers should include input clamping when the supply can spike in automotive or industrial environments.
How compact is the TC593002ECBTR package, and which PCB assembly processes does it support?
The TC593002ECBTR ships in a 3-pin SOT-23 package with tape-and-reel (TR) suffix, directly compatible with high-speed pick-and-place automated assembly lines. Its 3-pin SOT-23 footprint occupies less than 5 mm² of board area, making it one of the smallest negative LDO options available.
In which analog circuit designs is a fixed -3 V negative regulator like TC593002ECBTR most commonly used?
A fixed -3 V negative rail is commonly used to bias dual-supply op-amps, analog-to-digital converters, and audio amplifier stages that require symmetric ±3 V or asymmetric negative rails. The TC593002ECBTR's 10 V maximum input and fixed output simplify designs where a precision negative reference is needed without adjustable feedback resistors.
