Applications
The TC1187VCT713 is well-suited for powering low-voltage microcontrollers, sensors, and RF modules in battery-operated portable devices where the tight 0.27 V typical dropout enables efficient operation near the battery's end-of-life voltage. Its adjustable output range from 1.165 V to 5.5 V makes it versatile for post-regulation of bus voltages in embedded systems, IoT nodes, and wearable electronics. The 5-pin SOT-23 package is ideal for compact PCB designs requiring an LDO with minimal external components.

Frequently Asked Questions
How does TC1187VCT713's 0.27 V typical dropout voltage benefit battery-powered designs with a lithium-ion cell?
With a typical dropout voltage of only 0.27 V (maximum 0.4 V), TC1187VCT713 can maintain a regulated 3.3 V output even when a lithium-ion battery drops to around 3.6 V near end of discharge. This extends usable battery run time compared to LDOs with higher dropout voltages, and the 150 mA current capability covers most microcontroller and sensor loads in portable IoT devices.
What external components are needed to set the output voltage of TC1187VCT713, and what output range is achievable?
TC1187VCT713 requires only 2 external resistors connected to its feedback pin to set the output voltage anywhere from 1.165 V to 5.5 V. A standard resistor divider formula applies, and the 0.08%/V line regulation ensures the output remains stable across the input voltage range, making this 5-pin SOT-23 regulator easy to configure for 1.8 V, 2.5 V, 3.3 V, or custom voltages.
What is the procurement lead time for TC1187VCT713, and are there pin-compatible Microchip LDO alternates to manage supply risk?
TC1187VCT713 has a 5-week factory lead time from Microchip Technology. The TC1186 and MCP1700 series from Microchip offer similar adjustable or fixed LDO functionality in 5-pin SOT-23 packages with comparable 150 mA to 250 mA output current ratings, providing alternate sourcing options while maintaining the same PCB footprint to reduce supply chain risk.
