Frequently Asked Questions
How low is the dropout voltage of TC1071VCT713 at full load, and why does that extend battery life?
TC1071VCT713 has a nominal dropout voltage of 0.18 V and a maximum of 0.25 V at 100 mA output current. A lower dropout means the regulator continues providing a stable output rail even when the battery voltage drops within 0.25 V of the set output, extracting more usable capacity from a Li-ion or alkaline cell before the system shuts down.
Can TC1071VCT713 be turned off by a microcontroller to reduce power during sleep modes?
Yes, TC1071VCT713 includes an active-low shutdown control pin that allows a host MCU to disable the regulator output entirely. In sleep mode, the device draws minimal standby current, enabling system designers to achieve total power budgets in the single-digit microampere range for IoT and wearable products with infrequent duty cycles.
What output voltage flexibility does TC1071VCT713 offer compared to fixed-output LDOs?
TC1071VCT713 is adjustable, allowing designers to set any output voltage within its supported range using an external resistor divider. This removes the need to stock multiple fixed-voltage variants — the same part can be configured for 1.8 V, 2.5 V, 3.0 V, or 3.3 V rails by changing two resistors, simplifying BOM management for multi-voltage designs.
Which package does TC1071VCT713 use and how does its line regulation compare to typical LDOs?
TC1071VCT713 comes in a 5-pin SOT-23 package, one of the most compact through-hole-compatible SMD packages available. Its line regulation of 0.08%/V is tighter than many basic LDOs, ensuring that a 1 V change in input voltage shifts the output by less than 0.1%, which is important for analog sensor supply rails sensitive to supply noise.
